In 1838, the first three buildings of Fort Dallas began construction. The fort is named after U.S. Navy Officer Commodore Alexander James Dallas. The fort was built on plantation land leased from Richard Fitzpatrick. In 1842, at the end of the Second Seminole War, Fitzpatrick sold the land to his nephew, William F. English. English began reconstructing the plantation that same year. This included the construction of the slave quarters at the site of this marker.
