Open House New York Weekend October 17-18, 2015

For two days each October, the Annual Open House New York Weekend unlocks the doors of New York’s most important buildings, offering an extraordinary opportunity to experience the city and meet the people who design, build, and preserve New York.  

From historical to contemporary, residential to industrial, hundreds of sites across the five boroughs are open to visit, with tours, talks, performances, and other special events taking place over the course of OHNY Weekend. Through the unparalleled access that it enables, OHNY Weekend deepens our understanding of the importance of architecture and urban design to foster a more vibrant civic life, and helps catalyze a citywide conversation about how to build a better New York.
