Washington Heights holds stories and secrets that few New Yorkers know - paintings by Velazquez, El Greco and Goya in the lush Hispanic Society Museum, the graves of Clement Clarke Moore (author of The Night Before Christmas), John James Audubon and all of the Astors, as well as an intact Georgian mansion built in 1760, where Aaron Burr married the notorious Eliza Jumel and where George Washington watched the city burn in 1776. The city's best ghost story is here along with Paul Robeson's house, Sylvan Row, the site of the Polo Grounds and some splendid architecture. We'll cover the area north from West 155th Street (with digressions south into Trinity Cemetery) to West 162nd Street, and we'll meet outside the West 157th Street subway (1/9 lines) station, on the southeast corner.
