Ruh-roh!! Did you know Scooby-Doo 2: Monsters Unleashed (2004) was filmed right here at the Britannia Mine Museum? The movie captured the site just before our major 2005 Britannia Project transformation. Look closely to spot the iconic Mill No. 3 and other heritage buildings as the backdrop for the fictional Coolsville Mine. From mystery-solving hijinks to action-packed chase scenes, our historic industrial setting helped bring the spooky, larger-than-life world of Scooby-Doo to the big screen.
