Stewardship

The Architect of the Capitol is committed to the preservation and stewardship of the national treasures under its care. 

The Architect of the Capitol preserves the Capitol facilities and grounds while providing Congress with safe, comfortable, efficient, and modern office environments. The AOC is responsible for the vigilant stewardship of more than 30 buildings and leased spaces located both on Capitol Hill in Washington, D.C. and in remote facilities.

Examples of stewardship projects undertaken by the AOC include preserving and protecting the U.S. Capitol Dome exterior cast-iron surface in anticipation of a more comprehensive restoration in the future. In addition AOC made significant progress on the Capitol Complex Master Plan (CCMP). This plan provides a 20-year strategy to line up our infrastructure priorities, investments, and projects.

AOC is also responsible for the care, maintenance and preservation of a number of heritage assets entrusted to our care. AOC leads curatorial preservation projects such as the relocation and conservation of the Magna Carta display, the multi-phased restoration of the U.S. Botanic Garden’s Bartholdi Fountain, and the continued conservation of the Brumidi Murals in the Capitol.
