The museum is constantly adding new attractions and exhibits.
Most current exhibits are under constant change and expansion.
It truly is a venue where you can explore the unexpected. Many of the displays at the museum were under construction for better than three years prior to the 1997 opening. The idea to open a museum for the public to enjoy these treasures was not an initial goal of Bob and Gail Cassilly, the museum's founders. It started as a sort of private collection of fun and interesting sculptures and architectural wonders. The opening of City Museum came at a time when the city was questioning the viability of the downtown area.
