The National Park Service (NPS) has raised concerns about President Donald Trump’s proposed 250-foot-tall memorial arch, suggesting it could disrupt the historical significance of numerous sites near its intended location in Washington, D.C. The city’s monuments, buildings, and sites have been meticulously planned to reflect significant historical moments. These structures are strategically aligned to maintain visual and symbolic connections with others.
The proposed gilded arch recently received initial approval from a federal commission. However, the NPS reported that it would impact the ‘integrity’ of many historical properties. The report highlighted the potential alteration of ‘character-defining visual and spatial relationships’ among these properties.
The immediate project area is located within the Memorial Avenue Corridor cultural landscape. This area is a nationally significant historic designed landscape running from the Lincoln Memorial in Washington, D.C., to Arlington National Cemetery in Arlington, Virginia.
The report emphasized that the arch would break alignment between the Lincoln Memorial, Memorial Bridge, and Arlington House, previously home to Confederate Gen. Robert E. Lee. This alignment was originally designed to symbolically and physically unite the North and South across the Potomac River.
Numerous historic sites and structures, including the National Mall, the U.S. Capitol, Washington Monument, and Lady Bird Johnson Park, would be directly affected by the proposed arch. The project has encountered resistance despite moving smoothly through the approval process, partly due to Trump-appointed allies in planning bodies.
The White House has stated it will adhere to all legal requirements for constructing the arch. The arch, one of several projects pursued by Trump, is designed to leave a lasting impact on Washington. Its potential to alter the city’s iconic sightline sparked opposition and led to a lawsuit filed by veterans and a historian.
The arch design received early approval from the U.S. Commission of Fine Arts, composed of Trump appointees. It was also approved by the National Capital Area Planning Commission at its July meeting and will be revisited in September.
White House spokesman Davis Ingle commented that the Triumphal Arch in Memorial Circle aims to become an iconic landmark, enhancing the visitor experience at Arlington National Cemetery. It will serve as a visual reminder of the noble sacrifices of American heroes over 250 years.
The construction of the arch, along with Trump’s other projects, is currently subject to litigation. Plaintiffs, including three veterans and a historian, argue it lacks Congressional approval, an essential step for building a monument on National Park Service land in Washington, D.C.
Attorney Nicolas Sansone of Public Citizen Litigation Group, representing the plaintiffs, mentioned the significance of the NPS assessment. It confirms concerns about the impact on the symbolic and solemn area. Sansone emphasized the importance of Congressional authorization for such constructions.
