If you dig on great art and architecture, you’ll definitely want to look into this annual weekend-long event. Now in its sixth year, the New York Landmark Conservancy’s Sacred Sites Open House Weekend allows the general public to peruse the halls of churches, synagogues, temples, and meeting houses across the city. Over 45 sites are participating in the 2016 program, including the Bronx’s St. Anselm’s Church, which is modeled after the Hagia Sophia in Constantinople, the Victorian Gothic Church of the Covenant in Midtown, and the Cathedral of St. John the Divine in Morningside Heights. Tours are available for many of the sites. Visit the New York Landmarks Conservancy’s website for more details.
