It is the site of a fort that originally was in the form of an eight-pointed star with sixteen 30-foot (9.1 m) faces surrounded by a 10-foot (3.0 m) moat.

The 480-foot-long (150 m) parapet had earth walls 5 feet (1.5 m) high from which projected log palisades.

Within the parapet were four log blockhouses, smaller buildings for munitions and supplies, and wells.
