Fort DeSoto (Pinellas County, Florida)
Pinellas County · Florida · Spanish-American War

History & Significance
In 1849, Brevet Colonel Robert E. Lee and three other U.S. Army Engineers surveyed the area and recommended it as a site for coastal defenses. In 1898, when the United States became involved in a conflict in Cuba that led to the Spanish-American War, citizens of Tampa demanded military defenses for Tampa Bay.
Construction on the Mullet Key post began in November 1898, and within the first six months, a 275-foot wharf extending into Tampa Bay, a mess hall, office, stable, and a narrow-gauge railroad had been built. The first mortar battery was completed in May 1900, and more buildings were constructed between 1900 and 1906, which included a 100-foot-long barrack, hospital, guardhouse, a shop for blacksmiths and carpenters, a bakehouse, and a storehouse.
When construction was complete, the fort included 29 buildings, all of which were of wood construction with slate roofs. At its peak, the fort was garrisoned by 125 troops.
In 1909, the troops of Fort De Soto were transferred to Fort Morgan, Alabama, and the fort became inactive with just a caretaker detachment remaining. In 1977, the Fort De Soto batteries were placed on the National Register of Historic Places. In 1999, the quartermaster storehouse was reconstructed to become the Quartermaster Storehouse Museum.
