This is the mother church for this denomination and this explains some of why it's such a large church. It's not really close to many other historical attractions although Symphony Hall is almost right across the street but it was a short walk from one of the subway stops. We went inside the building and there were two greeters who filled us in with a few words about the building and their faith but it was brief. However, I had the feeling that they would be willing to talk for quite a while if we had been. They did answer a couple of questions we had about the building itself. Considering this church began in Boston it is a bit of history that is worth seeing. It is also just a one minute walk to the next door Mary Baker Eddy (their founder) Library and inside there is the unique Mapparium which gives you the chance to walk inside the globe for a look at the nations of the world from the 1930s. Everyone inside was very welcoming and pleasant which made it all a good experience.
