This is one side of the Mission Inn in Riverside, the side that I found the architecture to be the most interesting. The Mission Inn began life in 1876 as a 12 room adobe boarding house. Today it is a luxury hotel with 239 rooms and some amazing fine dining restaurants. There is a lot of history surrounding the Mission Inn and some say it is even haunted. The building is spectacular and tours are offered of the hotel and it even has a museum.
