Opinion for the Court filed by Circuit Judge GRIFFITH.
Late on the eve of the 265th birthday of Thomas Jefferson — Author of the Declaration of American Independence, of the Statute of Virginia for Religious Freedom, and Father of the University of Virginia— Officer Kenneth Hilliard of the United States Park Police arrested plaintiff Mary Brooke Oberwetter when she refused to stop what she describes as “silent expressive dancing” inside the Jefferson Memorial. She filed suit against Hilliard and the government alleging violations of her First and Fourth Amendment rights. The district court dismissed her complaint. For the reasons that follow, we affirm.
I
At quarter to midnight on April 12, 2008, Oberwetter and seventeen friends entered the Jefferson Memorial to “celebrate and honor the former President ... by ushering in his birthday with silent dance.” 1 Appellant’s Br. 4. According to Oberwetter, the dancing expressed admiration for Mr. Jefferson’s political legacy. “In the individualist spirit for which Jefferson is known, the dancers danced for the most part by themselves, in place, each listening to his or her music on headphones.” Compl. ¶ 13. The dancing took place inside the Memorial, a circular structure with a domed roof and colonnaded perimeter. “Apart from [Oberwetter] and her associates, and employees of the National Park Service, there were very few visitors to the Jefferson Memorial at the time of the dancing.” Id. ¶ 15.
A group of United States Park Police officers ordered the dancers to disperse. Oberwetter states that she did not immediately comply but removed a headphone from one ear and asked Officer Hilliard “why he was ordering her to leave, and what law she was violating.” Id. ¶ 18. Hilliard offered no explanation, but continued to insist that she stop dancing and leave immediately. Rather than complying, Oberwetter again asked Hilliard to “provide a lawful reason why she needed to do so,” but he “refused to offer any reason whatsoever for his demands, and instead arrested [her].” Id. ¶ 19. Oberwetter further alleges that Hilliard “used more force than was necessary ..., ripping apart her earbud, shoving her against a pillar, and violently twisting her arm.” Id. ¶21. The Park Police took her into custody for some five hours of processing, after which they cited her for “[interfering with an agency function” in violation of 36 C.F.R. § 2.32 (prohibiting “[threatening, resisting, intimidating, or intentionally interfering with a government employee or agent engaged in an official duty, or on account of the performance of an official duty”).
Three days later, Park Police officers visited Oberwetter’s home and gave her *549 two superseding citations — one for “interfering with an agency function,” and another for “[d]emonstrating without a permit” in violation of the National Park Service Regulations. See 36 C.F.R. § 7.96(g)(3)(ii)(C). On May 21, 2008, Oberwetter appeared before the district court to defend the charges. According to her complaint, the court found that “the prosecution ... was not properly before the Court and advised ... Hilliard that if he wished to proceed, he would have to properly prepare the matter for hearing.” Compl. ¶ 25. The Park Police have not pressed the matter since.
Oberwetter subsequently filed this suit, arguing that Hilliard’s enforcement of the Park Service Regulations to prohibit her expressive dancing violated her First Amendment rights to free speech and assembly. She sought injunctive and declaratory relief, stating that she “would again silently dance at the Jefferson Memorial to commemorate Thomas Jefferson’s birthday, by herself, and with other like-minded people, but refrains from doing so because she reasonably fears arrest, prosecution, fine, and/or incarceration if she were to do so again.” Id ¶ 26. She also brought three Bivens claims for money damages against Hilliard in his personal capacity, alleging violations of her First and Fourth Amendment rights.
The district court dismissed Oberwetter’s complaint for failure to state a claim, holding that she was lawfully arrested for violating the reasonable regulations that govern the Jefferson Memorial, a nonpublic forum reserved for the tranquil commemoration of Mr. Jefferson’s legacy.
Oberwetter v. Hilliard,
II
As a threshold matter, Oberwetter contends that the National Park Service misread its own regulations in treating her expressive dancing as unlawful. Ordinarily, we “accord an agency’s interpretation of its own regulations a high level of deference, accepting it unless it is plainly wrong.”
Howmet Corp. v. EPA,
The Regulations provide that, within the park areas of the National Capital Region, “[d]emonstrations and special events may be held only pursuant to a permit....” 36 C.F.R. § 7.96(g)(2). “Demonstrations” include:
picketing, speechmaking, marching, holding vigils or religious services and all other like forms of conduct which involve the communication or expression of views or grievances, engaged in by one or more persons, the conduct of which has the effect, intent or propensity to draw a crowd or onlookers. [The] term does not include casual park use by visitors or tourists which does not have an intent or propensity to attract a crowd or onlookers.
Id. § 7.96(g)(l)(i). 2
Oberwetter argues that her silent expressive dancing was not a demonstration because it was not “like” the enumerated activities of “picketing, speechmaking, marching, [or] holding vigils or religious services.” Id. § 7.96(g)(l)(i). Unlike those examples, she argues, her expressive dancing was not an “organized group activity in which a uniform message is passionately conveyed.” Appellant’s Br. 15. She further claims that her conduct falls within the exception for “casual park use.” Id. Dancing silently in place while listening to headphones, she says, is something that people do in the course of ordinary activity — waiting for the bus, standing on the sidewalk, etc. — and does not have the “effect, intent or propensity to draw a crowd or onlookers.” 36 C.F.R. § 7.96(g)(l)(i).
The district court properly rejected Oberwetter’s arguments. Under the Park Service Regulations, a demonstration need not be an “organized group activity,” but may consist of “one or more persons.”
Id.
Oberwetter’s expressive dancing falls within the spectrum of examples of prohibited activities, which range from “the boisterousness of picketing or speechmaking to the quiet solicitude of a vigil.”
Oberwetter,
Taking another tack, Oberwetter argues that even if she engaged in a demonstration inside the Memorial, she was free to do so because her group of silent dancers was never larger than 18 people. The Regulations allow for groups of 25 or fewer to demonstrate without a permit “provided that the other conditions required for the issuance of a permit are met.” 36 C.F.R. § 7.96(g)(2)(i) (emphasis omitted). She admits, as she must, that the Regulations state that “[n]o permits may be issued authorizing demonstrations or special events in ... [t]he Jefferson *551 Memorial, which means the circular portion of the Jefferson Memorial enclosed by the outermost series of columns, and all portions on the same levels or above the base of these columns, except for the official annual commemorative Jefferson birthday ceremony.” Id. § 7.96(g)(3)(ii). But, she argues, this is not a “condition” required for the issuance of a permit. In her view, there are no conditions at all for the issuance of a permit for demonstrations inside the Memorial, and so groups of 25 or fewer must be allowed to demonstrate there.
This argument can be readily rejected. As the district court rightly observed, the much more natural reading of the Regulations is that being outside of the Memorial is a required condition for any demonstration, meaning that, aside from the official birthday ceremony, no demonstrations of any size are allowed inside the Memorial.
Ill
The heart of Oberwetter’s complaint is her claim that the First Amendment protects her right to engage in silent expressive dancing inside the Jefferson Memorial.

Because the First Amendment “affords protection to symbolic or expressive conduct as well as to actual speech,”
Virginia v. Black,
We analyze Oberwetter’s claim under the familiar “public forum” doctrine, which divides government property into three categories for purposes of First Amendment analysis. The “traditional public forum” includes public areas that have “by long tradition or by government fiat ... been devoted to assembly and debate.”
Perry Educ. Ass’n v. Perry Local Educators’ Ass’n,
“The dispositive question is not what the forum is
called,
but what
purpose
it serves, either by tradition or specific designation.”
Boardley v. U.S. Dep’t of Interior,
The district court properly concluded that the area inside the Jefferson Memorial is a nonpublic forum. As a general matter, the interior space of national memorials has not traditionally “been used for purposes of assembly, communicating thoughts between citizens, and discussing public questions.”
Perry,
In creating and maintaining the Jefferson Memorial in particular, the government has dedicated a space with a solemn commemorative purpose that is incompatible with the full range of free expression that is permitted in public forums. 4 Oberwetter alleges that visitors to the Memorial regularly “talk loudly, make noise, [and] take and pose for photographs,” Compl. ¶ 10, but none of this conduct rises to the level of a conspicuous “demonstration.” For three-and-a-half decades, the Park Service Regulations have sought to “protect ] legitimate security and park value interests, including the maintenance of an atmosphere of calm, tranquility, and reverence in the vicinity of major memorials.” 41 Fed.Reg. 12,879, 12,880 (Mar. 29, 1976). *553 The Regulations specifically identify the interior of the Jefferson Memorial as a place where visitors may not engage in expressive activity that “has the effect, intent or propensity to draw a crowd or onlookers.” 36 C.F.R. § 7.96(g)(l)(i). Visitors to the Memorial interior must ascend a stairway, traverse a portico, and pass a sign that says “Quief/Respect Please” before entering. The Park Police patrol the area, and Oberwetter has pled no facts suggesting that they allow visitors to engage in disruptive demonstrations. Having thus created and maintained the Memorial as a commemorative site, the government is under no obligation to open it up as a stage for the roving dance troupes of the world — even those celebrating Mr. Jefferson.
That the Memorial is open to the public does not alter its status as a nonpublic forum. Visitors are not invited for expressive purposes, but are free to enter only if they abide by the rules that preserve the Memorial’s solemn atmosphere. As the Supreme Court has observed, an area “is not transformed into ‘public forum’ property merely because the public is permitted to freely enter and leave the grounds at practically all times.”
United States v. Grace,
Nor is this case like
Grace,
where the Supreme Court held that the grounds surrounding the Supreme Court building could not be deemed a nonpublic forum because there was “no separation, no fence, and no indication whatever to persons stepping from the street ... that they [had] entered some special type of enclave.”
Having determined that the Jefferson Memorial is a nonpublic forum, we have little trouble concluding that the Park Service Regulations are “viewpoint neutral and reasonable in light of the purpose [of] the forum.”
Marlin v. D.C. Bd. of Elections and Ethics,
We have noted previously that the Park Service has a substantial interest in promoting a tranquil environment at our national memorials.

Finally, we turn to Oberwetter’s claims against Officer Hilliard under
Bivens v. Six Unknown Named Agents,
Hilliard’s alleged conduct did not violate Oberwetter’s clearly established constitutional rights. She had no First Amendment right to stage an unlawful performance inside the Jefferson Memorial, and in doing so created the cause for her own arrest. She alleges that Hilliard acted out of malice, arresting her for no good reason after she questioned his authority. But in fact her arrest was prompted not merely by her questioning Hilliard, but rather by her failure to comply with his lawful order during the course of her unlawful conduct. In any event, Hilliard’s motive would not affect the existence of probable cause, which depends “on an objective assessment of the officer’s actions in light of the facts and circumstances confronting him at the time ... and not on the officer’s actual state of mind at the time the challenged action was taken.”
Maryland v. Macon,
*555
Oberwetter’s remaining
Bivens
claim is that Hilliard violated the Fourth Amendment by using excessive force when he pulled her arm behind her back and pushed her up against a stone column during her arrest. In general, police officers have authority to use “some degree of physical coercion” when subduing a suspect,
Graham v. Connor,
Although Oberwetter’s alleged violation was far from “sever[e],” her complaint nonetheless makes clear that Officer Hilliard’s use of force was not excessive. Most instructive on this point is
Wasserman v. Rodacker,
The same factors are dispositive in the present case. Oberwetter admits in her complaint that before she was arrested she twice refused Hilliard’s order to stop dancing and leave the Memorial. She also admits that she was accompanied by a group of 17 other people at the time, which in our view could have caused Hilliard to be reasonably worried that events might get out of hand. This is especially true given the lateness of the hour and the unusual activity of the crowd, whose intentions he did not know. Under such circumstances it was not clearly unreasonable for Hilliard to take decisive action to subdue Oberwetter quickly and forcefully, thereby reducing the risk of interference or escape. Given that some force may have appeared reasonably necessary, Hilliard’s alleged actions were not markedly different from what we would expect in the course of a routine arrest. As in
Wasserman,
the fact that Hilliard did not cause Oberwetter any serious bodily injury tends to confirm that the use of force was not excessive.
See also Wardlaw,
In light of these considerations, we agree with the district court that Oberwetter’s complaint has failed to state a sufficient claim that Hilliard’s actions were beyond the pale of reasonableness as established by our case law.

The judgment of the district court is Affirmed.
Notes
. For his part, Mr. Jefferson is on record discouraging celebration of his birthday. "On Mr. Jefferson’s accession to the Presidency [visitors] had waited on him, requesting to be informed, which was his birthday, as they wished to celebrate it with proper respect. 'The only birthday I ever commemorate,’ replied he, 'is that of our Independence, the Fourth of July.’ ” The First Forty Years of Washington Society 398 (Gaillard Hunt ed., Scribner's Sons 1906).
. On January 3, 2011, the Park Service issued a notice of proposed rulemaking that "would revise the definition of demonstration at 36 C.F.R. 7.96(g)(l)(i) by eliminating the term 'intent or propensity’ where it appears in the definition and replace it with 'reasonably likely.' " 76 Fed.Reg. 57, 57.
. Because Oberwetter brings an as-applied rather than a facial challenge, we do not address whether the Regulations could survive a challenge on grounds of substantial overbreadth.
See Wash. State Grange v. Wash. State Republican Party,
. We are mindful that forum determinations are typically fact intensive, and that we lack a factual record here because the district court dismissed this case on the pleadings. We press ahead nonetheless because the salient features of the Memorial are "generally known within [our] territorial jurisdiction” and "not subject to reasonable dispute.” Fed.R.Evid. 201(b).
