Built in 1766, this is not only the oldest church in the city, it’s the only public space to be in continuous use since the Colonial era. The design of the church, with its Ionic columns and huge pediment, was based on that of St. Martin-in-the-Fields in London, though I think the overall effect of this church is not nearly as graceful. Still, St. Paul’s is redolent with history: George Washington had a pew here (now marked by a plaque), and he came directly to the church after his inauguration to pray and give thanks. On 9/11, the church miraculously survived a rain of fiery metal when the Twin Towers collapsed. It served as a focal point for the volunteer effort that ensued as hundreds of people came from all over the world to search for survivors and then human remains. Many slept at St. Paul’s and took meals here (an exhibit in the church details this history). Free guided tours available every Friday at 3pm.
