Friends Meeting of Washington is being featured on this tour, and is the site of the tea. The Dupont Circle Citizens Association will hold its 49th Annual House Tour on Sunday, October 16 from 12pm to 5. This year will feature the Northwest section. Topographically, the northwestern edge of the Dupont Circle neighborhood lies at the foot of the Wicomico-Sunderland Escarpment, part of the Atlantic Seaboard fall line, the outer boundary of the original L'Enfant City. In fact, Florida Avenue, which forms the spine of this year's tour, was originally named Boundary Street. Tour-goers will begin in the lowlands of P Street among grand townhouses and rise to the Florida Ave rim where unique buildings featuring panoramic views will be open to the tour – the American Geophysical Union and the new Hepburn Apartments adjacent to the Hilton.
