Built in the 1760s by British colonel Roger Morris as a breezy hilltop retreat called Mount Morris, it was used as a headquarters by George Washington during the Revolution. (Yep, Washington really did sleep here!)
After her husband died, social-climbing Eliza’s new spouse, Aaron Burr, moved in—a fascinating story for another post.
Anyway, two hundred years later, the Georgian-Federal style mansion is a museum. But perhaps the most interesting relic is a slab of stone on the grounds outside the house.
It’s a mile marker. Before GPS, maps, and even a city street grid, mile markers were set in the ground on roads outside the city. They let travelers know how far they were from today’s downtown.
An accompanying plaque explains that the mile marker was originally placed in 1769 on Kingsbridge Road, which ran along Broadway, according to Myinwood.net.
Mile markers have been disappearing for generations. Apparently a nine-mile marker remained in Upper Manhattan until as recently as 1991.
