The cathedral is located in Washington, D.C., the capital of the United States. The structure is of Neo-Gothic design closely modeled on English Gothic style of the late fourteenth century. It is the second-largest church building in the United States, and the third-tallest building in Washington, D.C. The cathedral is the seat of both the Presiding Bishop of the Episcopal Church, Michael Bruce Curry, and the bishop of the Diocese of Washington, Mariann Edgar Budde. Over 270,000 people visit the structure annually.
