Located on a prominent rock outcrop in the North Woods, the Blockhouse was part of a fortification system built to defend New York from the British during the War of 1812. This weekend only, visitors will find the Blockhouse unlocked and open for exploration. Guides will be on hand to answer questions, provide historical context, and share photos during this unique opportunity to enter the only structure located in Central Park that actually predates it!
