Trinity Church in Boston is very easy to find, but tickets are charged, so I didn't go in, the staff arrived well, let us take pictures in the hall. There is a staircase on the left, you can go down to the underground to buy souvenirs, we bought a lot of gold and silver small coins, there are various patterns cast on the top, very cute, send people very good! Go to the outside of the church to see, the whole building is also relatively magnificent, not a completely old-fashioned building, but an architectural style that integrates ancient and modern, which can be regarded as some characteristics. After shopping, you can continue to visit the central library opposite.
