District of Columbia General Hospital The District of Columbia General Hospital, previously the Gallinger Municipal Hospital, was a hospital located in Washington, D.C.. It was operational from 1806 to its controversial closing by mayor Anthony A. Williams in 2001, as the city was trying to cut costs while recovering from bankruptcy. At the time of its closure, it was the only public hospital located within the District. Originally located in Judiciary Square it moved to 19th and Massachusetts, SE in 1846. At the turn of the century, efforts to open a new public hospital at 14th and Upshur were opposed by residents.
