Heritage Open Day: A historic lighthouse overlooking nature-rich clifftop grasslands, coastal park and rugged coastline. Visit Souter Lighthouse free of charge. Opened in 1871, Souter Lighthouse was a marvel of its age and remains an iconic beacon. Hooped in red and white, it stands proud on the coastline midway between the Tyne and the Wear. It was the first lighthouse in the UK designed and built to be powered by electricity. Souter is a special place to visit at any time of year.
