John A. Wilson Building (District Municipal Headquarters)

The John A. Wilson Building at 1350 Pennsylvania Ave NW serves as the seat of Washington, D.C.'s municipal government, housing the offices of the Mayor and the Council of the District of Columbia. Completed in the early 20th century as the District Building, it was renamed for longtime D.C. councilman and mayoral candidate John A. Wilson in 1994. The building's Beaux‑Arts façade and central location on Pennsylvania Avenue make it a longstanding civic landmark for local governance and public ceremonies.
