Trump Proposes Converting Washington D.C. Arch into Military Complex Amid Legal Challenges
US President Donald Trump announced plans to transform a proposed 250-foot triumphal arch in Washington D.C. into a military facility, citing national security requests. The project faces lawsuits over congressional approval requirements and concerns regarding historic sightlines and aviation safety.
US President Donald Trump announced on Sunday that his proposed 250-foot (76-meter) triumphal arch in Washington D.C. will be converted into a "top grade military complex." The structure, intended for a circle adjacent to the Memorial Bridge across the Potomac River from the capital and just outside Arlington National Cemetery, was originally designed as a monument but will now reportedly house drones, snipers, and ammunition.
In a post on Truth Social, Trump stated that the conversion was made at the "strong request" of the US military for "national security purposes." He claimed the facility would accommodate large numbers of drones, with snipers positioned on the roof and plaza, alongside quantities of sniper ammunition. No specific threats were identified in the announcement. When reached for comment regarding these claims, the Department of Defence declined to provide additional details.
The proposal has sparked significant legal and regulatory opposition. A group comprising three veterans and an architectural historian has filed a lawsuit to block the project, arguing that it requires approval from Congress rather than solely from the U.S. Commission of Fine Arts. Attorney Nicolas Sansone, representing the litigants, asserted that manufacturing a national security justification does not cure the project's illegality because Congress has not authorized the arch.
Regulatory bodies have also raised concerns. Last week, the Federal Aviation Administration determined that while the arch would not pose a hazard to aircraft—despite its proximity to Reagan Washington National Airport—it required an "eternal flame" on top. Conversely, the National Park Service warned that the structure could have "adverse effects to historic properties" and called for additional planning before construction begins. Critics argue the massive scale of the arch, which would dwarf the nearby 99-foot Lincoln Memorial and stand half as high as the Washington Monument, threatens historic sightlines between the memorial and Arlington National Cemetery.
Renderings of the original design show the arch clad in granite, topped by a golden winged Lady Liberty statue flanked by two gold eagles, and inscribed with "One Nation Under God" and "Liberty and Justice for All." Groundbreaking was expected to begin this month, coinciding with the 250th anniversary of the Declaration of Independence.
This initiative is part of a broader set of construction projects by Trump aimed at reshaping the capital. These efforts include a $400 million White House ballroom, renovations to the Kennedy Center, and refurbishing the Lincoln Memorial Reflecting Pool. Additionally, public access to running and biking paths in East Potomac Park has been reduced due to golf course rebuilding.
