Portavant Mound, Archaeological mound in Emerson Point Preserve, Manatee County, Florida, US.

Portavant Mound is an archaeological earthwork in Emerson Point Preserve, a nature area on Florida's west coast. The structure consists of earth and shell materials and offers views of surrounding wetland and coastal habitats.

The Portavant Mound is one of fifteen or more temple mounds built by the Safety Harbor culture, which existed from 900 to 1725 and centered on the Tampa Bay area. The mound was added to the National Register of Historic Places on December 23, 1994. A stabilization project has since aimed to protect it from river erosion, looting, foot traffic and exotic vegetation.

The name Portavant comes from the Portavant family, who owned land on Snead Island; the mound is also called the Snead Island Temple Mound. It is one of fifteen or more temple mounds of the Safety Harbor culture (900–1725) around Tampa Bay, built from soil mixed with midden debris.

To reach this structure, you walk on hardened trails and wooden boardwalks that run through the preserve. The ground is flat and fairly easy to traverse, and you can explore from various entry points.

This site was built without a ramp-style entrance, which sets it apart from other similar structures in the region. An adjacent lower platform suggests there were multiple zones for different purposes.
