🧀 Did You Know?

These orange spots on the ceiling of the South Cell Block of the Historic SDG Jail are actually old slices of cheese. They were thrown during a riot prior to the closure of the jail in 2002, and they remain there to this day!

Come take a look for yourself with a guided or self-guided tour!

This is the last weekend of the season, so don't delay!
