It resembles an Aztec-inspired fire lookout, but this wooden tower is actually one real-estate developer’s vision gone utterly awry. In the 1920s Richter C Perky had the bright idea to transform this area into a vacation resort. There was just one problem: mosquitoes. His solution? Build a 35ft tower and move in a colony of bats (he’d heard they eat mosquitoes). He imported the flying mammals, but they promptly took off, leaving the tower empty.
