A promontory is a raised mass of land that projects into a lowland or a body of water (in which case it is a peninsula).
Located at the edge of a landmass, promontories offer a natural defense against enemies, as they are often surrounded by water and difficult to access.
The fort was located at the confluence of the Allegheny and Monongahela rivers, providing an additional layer of defense.
These forts were often located on isolated peninsulas or headlands and were difficult to access, making them ideal for defending against enemy attacks.
The ancient town of Ras Bar Balla in southern Somalia is another example of a promontory fort.
