The Venice Stronghold is a Janus stronghold in the city of Venice, Italy. It appears in Book 2. It is filled with, according to Dan, "million-dollar paintings," and it also has modern art pieces and Janus performers. In the background, music from famous Janus musicians plays on "Radio Janus". It is located in the back of a music store, Disco Volante, and can only be accessed if you listen to the right song. In this case it is Mozart's Adagio KV617.
