The National Park Service has determined that a proposed 250-foot-tall arch honoring former President Donald Trump could negatively affect dozens of historic sites across Washington, D.C., and Northern Virginia. The finding comes from an internal review obtained by The New York Times, which assessed the structure’s potential visual and cultural impact.
The arch, if built, would rise near the National Mall, altering sightlines that currently frame landmarks such as the Lincoln Memorial, the Washington Monument, and the U.S. Capitol. The review notes that the structure’s height would intrude on protected viewsheds established under federal preservation laws. Those laws require federal agencies to consider how construction projects affect historic properties listed on the National Register.
Arlington National Cemetery would face particular disruption, according to the report. The arch’s placement would compromise views from the cemetery’s Memorial Amphitheater and the Tomb of the Unknown Soldier, where sightlines are considered sacred to commemorative ceremonies. The Park Service flagged these impacts as “adverse” under the National Historic Preservation Act.
The review identifies dozens of additional properties that could suffer diminished visual integrity, including the Jefferson Memorial, the Franklin Delano Roosevelt Memorial, and the Martin Luther King Jr. Memorial. It also lists residential neighborhoods in D.C. where historic districts would lose their current open vistas toward the river and the city’s core.
Supporters of the arch argue that it would serve as a patriotic symbol and enhance the nation’s capital, drawing comparisons to the Gateway Arch in St. Louis. But the Park Service’s assessment suggests that its scale and location, still under final consideration, could overshadow existing monuments rather than complement them.
The project faces a series of legal and administrative hurdles before construction can proceed. Federal reviewers must complete a full environmental impact statement, and any final approval would likely trigger litigation from preservation groups, who have already voiced opposition. The review’s findings do not kill the proposal but add a significant layer of scrutiny.
The arch’s foundation would require excavation near the Tidal Basin, an area prone to flooding and already undergoing separate restoration efforts. Engineers have noted that construction could complicate ongoing infrastructure repairs, though no formal cost estimates for the entire project have been released. The Trump Organization, which has promoted the plan, has not commented on the Park Service’s findings.
This review marks a notable instance of a presidential monument facing formal opposition from within the federal government’s own preservation apparatus. Past projects, such as the Vietnam Veterans Memorial, also sparked controversy during planning, but none have involved a structure of this height or location. The outcome will likely set a precedent for how future commemorative projects are evaluated.
Public comment periods will begin later this year, allowing residents and historians to weigh in on the proposal. The Park Service has scheduled hearings in both D.C. and Virginia for September, with a final decision expected by mid-2027. Until then, the arch remains a concept, not a certainty, constrained by the very regulations it would stand among.
