They closed early owing to weather the first time I went to see the place. The second day I went was Saturday and they were open to 1700. I went on the 30minute 1600 tour. The guide told you all about the founding of Christian Science, a bit about how Mary Baker Eddy came to discover the practice and then gave us a detailed guided tour of the main(newer, larger) church and the original church. The guide was very knowledgeable and passionate about this job. All the staff I encountered here were really friendly. Photos welcome.
