George Halpin Senior designed the major light of Mine Head lighthouse. Constructed of red sandstone the structure stands on top of the steep cliffs above the Celtic Sea.
The lighthouse was built in 1851 and has a 22 m (72 ft.) white tower with a black band. It was converted to electricity in September 1964. The beacon flashes white and red every 2.5 sec. and has a range of 52 km (28 nautical miles).
