I am always interested in the history of buildings, so I will be writing (hopefully every weekend) a feature about the history of different buildings with in the D.C. area. Up this weekend is the Metropolitan AME Church, located on M Street between 15th and 16th streets downtown.The church hosted Frederick Douglass’s and Rosa Park’s funeral, had President Taft, Eleanor Roosevelt, and Bishop Desmond Tutu as speakers, and held pre-inaugural prayer services for President Clinton.
