Saint Paul's Church National Historic Site
Saint Paul's Church National Historic Site is located in Mount Vernon, NY 10550 in Westchester County.

"A large undertaking for a relatively small town, the church was not complete when the political and military disruption of the American Revolution rocked the area, halting construction. On the eve of the war, most of the exterior was in place, and the tower had been erected about 2/3 of the way to the present steeple, but the interior was little more than a dirt floor. The community was still worshipping in the wooden meetinghouse. Yet, even in its unfinished form, the church was the largest, best built, centrally located building in the vicinity and since it was unlocked and unused during the War for American Independence, it became the obvious location for a field hospital during local campaigns. It was used by the American, British and Hessian armies. The need for firewood as fuel by those forces led to the complete disassembling of the older meetinghouse by the war’s conclusion."

Old Dutch Church
Visit the Old Dutch Church in Sleepy Hollow. "It stands on a knoll, surrounded by locust-trees and lofty elms, from among which its decent whitewashed walls shine modestly forth, like Christian purity beaming through the shades of retirement. A gentle slope descends from it to a silver sheet of water, bordered by high trees, between which, peeps may be caught at the blue hills of the Hudson." by Washington Irving in "The Legend of Sleepy Hollow."

Lyndhurst Historic Site
Visit Lyndhurst in Tarrytown, overlooking the Hudson River. Lyndhurst is considered one of America's finest Gothic Revival mansions.
