Lough Swilly

Lough Swilly (Loch Súilí in Irish) in Ireland is a fjord-like body of water lying between the eastern side of the Inishowen Peninsula in County Donegal and the rest of northern Donegal.

At the northern extremeties of the lough are Inishowen Head and Dunaff Head. Towns situated on the Lough include Buncrana on Inishowen and Rathmullan on the western side. At the southern end of the Lough lies Letterkenny.

The Lough was used as an anchorage by the Royal Navy during World War I. The British also built a number of forts to protect the Lough and the remains of these can be seen at Lenan Head, Dunree (now a museum) and at Buncrana.
