The Cairo apartment building is located at 1615 Q Street NW in Washington, D.C.
It is a landmark in the Dupont Circle neighborhood and the District of Columbia's tallest residential building.
Designed by architect Thomas Franklin Schneider and completed in 1894 as the city's first "residential skyscraper", the 164-foot tall brick building spurred local regulations and federal legislation that continue to shape Washington's cityscape.
Today, the Cairo is a condominium building, home to renters and owners of apartments ranging in size from small studios to multi-level two- and three-bedroom units.
