Old Fort Park

Old Fort Park is the historic site of Fort Pierce, a U.S. Army supply depot built during the Second Seminole War. The modern city of Fort Pierce takes its name from this installation. Located along the Indian River, the area was once home to a freshwater spring, making it a key settlement site for early inhabitants. The Ais people lived here for centuries, relying on the river for fishing and trade. However, disease, invasions, and enslavement led to their disappearance by 1740.

In 1838, the U.S. Army selected the site for Fort Pierce due to its high elevation and access to freshwater. The fort was never involved in battle and was abandoned in 1842. A fire destroyed it in 1843, leaving only the mound behind. Today, the park features sabal palmettos and mossy oaks, similar to those used in the fort’s construction.

Visitors can walk up the mound for a clear view of the Indian River. Along the shoreline, remnants of the underground stream can still be seen. The Fort Pierce Lions Club has added informational signs throughout the park to provide historical context. The site also contains an ancient Ais burial mound, preserving its historical significance.
