Trinity Church in Boston is a beautiful and stunning National Historic Landmark, recognized as one of the most architecturally significant buildings in the U.S. The outside is gorgeous, surrounded by modern skyscrapers, but the breathtaking inside is a well laid out edifice over 100 years old. More than 100,000 people visit annually to tour, pray, or listen to a concert. It is a thriving parish that bustles with activity, where everyone is welcome, accepted, and embraced as a friend. A visit is very cool and worthwhile, with an audio explanation about its history. There is a $10 entry fee for adults to tour, which is worth it for the experience and photos.
