Even if you’re not a godly guy or gal, New York Landmarks Conservancy offers a great chance to take a peek at gorgeous houses of worship across all five boroughs with its annual Sacred Sites Open House Weekend. This year's tours are organized around the theme "Congregations and Communities: 50 Years of Sacred Sites."
Participating congregations will showcase their buildings, histories and community programs through lectures, musical performances, and special guided tours. It's free to attend. Righteous.
