The History of Ballast Key

Ballast Key has a rich history that dates back to the early days of Key West’s development. The island got its name from the ballast rocks left by 19th-century ships that used the area as a dumping ground before loading cargo from Key West’s busy port. Over time, the uninhabited island became a sanctuary for wildlife and a hidden treasure in the Lower Keys.

In the 20th century, Ballast Key found its most famous steward in David Wolkowsky, a visionary developer often referred to as “Mr. Key West.” Wolkowsky purchased the island in the 1970s and transformed it into a private retreat, building a stunning home and preserving much of the natural environment. His efforts ensured that Ballast Key remained both a haven for humans and a sanctuary for local flora and fauna.
