National Capitol Columns, Architectural monument in Northeast Washington, D.C., United States
The National Capitol Columns consist of twenty-two sandstone shafts with Corinthian capitals arranged in an open-air gallery within the National Arboretum. These columns form a classical portico structure and are complemented by a reflecting pool that creates mirror images of the historical elements.
These columns originally supported the Capitol's East Portico from 1828 until 1958, when they were removed during a major expansion of the building. They were later relocated to the Arboretum, where they were reinstalled on original Capitol foundation steps.
The columns showcase early American neoclassical design and reflect how federal building standards changed in the nineteenth century. Visitors can examine these architectural details up close and see how they once formed part of the nation's most important government structure.
The location is accessible daily during regular Arboretum hours with no entry fee required. The walkways to the columns are well-marked and relatively flat, making the visit straightforward for most people.
The columns rest on actual foundation steps from the original Capitol building, a detail many visitors overlook. This reuse connects two buildings through their architectural pieces and tells a story of transformation and preservation.
