Mainz Cathedral or St. Martin’s Cathedral (in German Mainzer Dom, Martinsdom or – officially – Der Hohe Dom zu Mainz)which is located near the historical center and pedestrianized market square of the city of Mainz, Germany. This 1000 year-old Roman Catholic cathedral is the site of the episcopal see of the Bishop of Mainz. Bruce especially is finding the church architecture very interesting. German and Italian towns and architecture are so vastly different. We went back to the boat to spend a nice evening there. The dinners are so nice and they always have great entertainment. We have been enjoying conversation with the other guests on the boat. Tonight was a female singer that sang pop to Christmas tunes to opera. She was very good. Tomorrow is a day in Heidelberg!
