St. Ann & the Holy Trinity Church, a national landmark building, will again join over 250 other significant sites in welcoming visitors during the 17^th annual Open House New York Weekend, a citywide celebration of architecture, urban design, and New York City. Every October, buildings and projects across New York’s five boroughs – from infrastructure facilities to cultural spaces and from workspaces to private residences – open their doors to the public for tours and talks with architects, urban designers, historians, preservationists, and city leaders. Sites include variety of building types from historic farmhouses built in the city’s earliest days, to Art Deco theaters that capture the exuberance of the Jazz Age boom, to new buildings at the cutting edge of design and technology.
