This is the oldest building in the city, built in June of 1997, and transported to my new apartment when I moved in 1998, which was when I started on the rest of the city.
The following events and exhbits are currently on display: "Dianosaur!", "The Wonderful World of Widgets", "Early Space Exploration", "Under the Sea", along with several others.
It is only 1 story tall, not counting the fact that the main exhibit hall has a 2-story vaulted cieling. It has a nice dome cieling, furnished from a diver's bubble. This building is the only structure in my city that does not fit my "taller than it is wide" rule, only because it was grandfathered in.
