Quirky Ambition: The Rise and Fall of Sugarloaf Key’s Mysterious Bat Tower

The Bat Tower on Sugarloaf Key, located in the Florida Keys, is one of the region’s most unusual and mysterious landmarks. Built in 1929 by Charles P. Haskell, a wealthy industrialist, the tower was intended to help control the island’s mosquito population. Haskell believed that by constructing a tower to attract bats, he could use their natural ability to consume insects to reduce the pests.

The three-story, cylindrical concrete structure was designed with small entry holes to encourage bats to roost inside. Haskell even placed some bats inside to get the colony started. However, the bats quickly abandoned the tower, never to return. Despite the initial attempt, the bats never took to the structure, and it’s unclear why—whether the design was unsuitable, the location too remote, or the tower simply didn’t offer the right conditions for bat habitation. As a result, the Bat Tower never fulfilled its intended purpose and fell into disrepair over the years.

In 2017, the Bat Tower met its final fate when it was severely damaged by Hurricane Irma, which tore through the Florida Keys. The storm caused extensive destruction throughout the region, and the Bat Tower was left in ruins, its once-ambitious structure now largely gone.

Today, the Bat Tower remains a symbol of both quirky historical ambition and failure. Although it is no longer standing, it continues to be remembered as one of the Florida Keys’ most peculiar and eccentric landmarks, a reminder of a man’s attempt to solve an ecological problem with an innovative, yet ultimately unsuccessful, solution.
