Fort Independence

Fort Independence is a granite fortress on Castle Island in South Boston, built across multiple periods with sections containing gun emplacements, bastions, and protective walls throughout the structure. The installation was positioned to overlook and defend the harbor entrance from enemy approach.

The site started in 1643 as Castle William and underwent multiple rebuilding phases before the current structure was completed between 1833 and 1851. This long construction history reveals how Boston's military needs evolved over time and how each generation modified the installation to match their requirements.

The fort reflects how Boston's waterfront was protected across different eras, with each construction phase leaving marks on the stone walls and layout. Walking through it today, you see how military priorities shaped what the structure looks like and how it was built to work.

The fort is open from dawn to dusk for self-guided exploration, with walking paths that loop around the structures and offer various viewpoints of the harbor. Wear sturdy shoes since the paths are uneven in places, and weather protection is useful as the location is exposed to wind and water.

Edgar Allan Poe was stationed here in 1827 and drew inspiration from a local incident for one of his well-known stories. The exact details of what happened remain somewhat mysterious and are part of the place's ongoing conversation among visitors.
