This charming 1799 fieldstone country church, which is Episcopalian, stands on what was once Governor Peter Stuyvesant's bouwerie, or farm. It's Manhattan's second-oldest church, and both Stuyvesant and Commodore Matthew Perry are buried in vaults here. Check out the gorgeous modern stained-glass windows on the balcony, which replaced the more traditional windows (like those on the ground level) after a fire in the late '70s. Over the years St. Mark's has hosted many avant-garde arts events, including readings by poet Carl Sandburg and dance performances by Martha Graham and Merce Cunningham. The tradition of art partnerships has continued with Danspace, the Poetry Project, New York Theatre Ballet, and LocoMotion, which give performances throughout the year. Services are held Sunday at 11.
