Old buildings like this that have been changed into tourist attractions are great. There are rarely alarms, staff are usually just at the front, and you're only stopped by a locked door. Every once in a while one of those locks gets forgotten, and away you go!

You got this one right . . If I had more time, I would have liked to get into the basement (read: dungeon) where one would be promised many museum-quality items to photograph in their NATURAL setting.
