Prospect House, Georgian mansion in Georgetown, United States.
The Prospect House stands at 3508 Prospect Street with a symmetrical facade, three floors, and an octagonal protrusion added during the Victorian period.
William Thornton, the architect of the United States Capitol, designed this residence in 1788 for General James Maccubin Lingan, a founding figure of Washington D.C.
President John Adams and the Marquis de Lafayette were among the distinguished guests who visited this residence during its early years of existence.
The property maintains its original architectural elements while featuring modern amenities including gardens, a veranda, a gazebo, and a swimming pool.
A remarkable U-shaped stairway connects all three floors of the house, demonstrating the architectural ingenuity of late 18th-century design.
