Sonic World Adventure Rush!
Robotnik's Sky Base was his first ever flying fortress, and went down just as quickly it went up.
After Sonic destroyed it, the smoldering ruins were left to rot and rust in the trees nearby Gimmick Mountain. No one had the means or equipment to clean up the mess, so it is now fenced off.
