Knockalla Fort

Knockalla Fort is a triangular fortification on the Lough Swilly coast with distinctive rounded towers and dual defensive walls. The structure spans multiple levels with casemates, storage magazines, and gun platforms that overlook the entire harbor area.

The fort was built in 1812 and 1813 in response to military threats during the Napoleonic Wars. It was part of a broader defense strategy protecting the Irish coast from potential invasions.

The name comes from Irish words referring to the surrounding landscape. Visitors can still see how the gun positions were arranged and understand how soldiers once watched over the harbor from this spot.

The fort sits directly on the coast and is surrounded by a dry moat, with rough paths guiding visitors through the site. The best time to explore is during calm weather, as the exposed positions can become windy and wet.

The fort's lower gun platforms featured special rotating mounts that allowed heavy cannons to be aimed quickly in different directions. This technical innovation shows the advanced understanding of artillery positioning that Irish engineers achieved at the time.
