Fort Foster

Fort Foster (now known as Fort Foster Historic Site) was a fort in central Florida, located 9 miles (5.6 km) south of current-day Zephyrhills in Pasco County. It was built in December 1836 under the direction of Lt. Col. William S. Foster on the site of Fort Alabama. This had been abandoned by federal troops at the end of the Seminole Wars, booby trapped and exploded by gunpowder on the reported approach of Seminole.

The site was significant for a battle in 1837 during the Seminole Wars, when United States forces resisted a Seminole attack. The following year, the US abandoned the fort because of disease among its forces.

Fort Foster was reactivated as needed from time to time in 1837, 1841-1842, and 1849 to meet the needs of the military when Seminole activity threatened.

The fort site was added to the U.S. National Register of Historic Places on June 13, 1972. A replica of the fort was constructed at the site by the state, and it is owned and operated by the Florida State Park system. It is in the Hillsborough River State Park.
