Cathedral of St. John the Divine

First founded in 1681, the Cathedral of St. John the Divine is on its third iteration. It's been destroyed twice by earthquakes and rebuilt from the ground up. The current version has been standing since 1845, but just to be on the safe side, plan your visit for a clear day with little chance of weather.

Jokes aside, it's this cathedral's staying power that makes it such a fascinating visit for tourists. The interior is definitely in need of repairs, and its décor isn't as magnificent as other structures of the same era, but you should at least stop by for a quick visit and picture-taking opportunity (at least of the dual bronze St. John statues on the outside). Some visitors suggest you make your trip to the Cathedral of St. John the Divine a two-for-one; stop by St. John's Saturday Morning Market for some shopping before heading back to your cruise ship or hotel.

You could stop by the cathedral for church services on Sunday morning, but it's also open for day tours during the week. Donations for the church's preservation are requested, but not required. Visit the church's website for more information.
