Portora Lock was built in the 1950s - replacing an older 1880’s lock - and built as part of the Erne Drainage and Navigation Scheme.
It helps manage water levels across Lough Erne and let boats pass between the upper and lower loughs.
It is located right next to the historic ruins of Portora Castle, which was built in 1613, making it a scenic and historically rich passage for cruisers and boaters.
