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. Fort Foster was originally built in December 1836 under the direction of Lt. Col. William S. Foster on the site of Fort Alabama. On December 1, 1836 Colonel Foster arrived at the site with 430 men to rebuild the fort and bridge that had been destroyed months earlier.
