English: Guarding the High Light A square type 22 pillbox, located in the field below Happisburgh lighthouse; it was constructed in 1940/41, forming part of the Norfolk coast defences. A second, polygonal, pillbox can just be glimpsed in the background (Defence of Britain database reference number S0000878). The pillbox with red-brick shuttering seen in the foreground has the Defence of Britain database reference number S0000880. Happisburgh Lighthouse was built in 1790; it is the oldest working light in East Anglia, and the only independently run lighthouse in Great Britain. Two lighthouses were built after 70 sailing ships and 600 men were lost during a severe winter storm in 1789 - Low Light was situated on the cliftop but has since tumbled into the sea, and High Light, located 400 yards inland from it, which still stands. Its tower is 85ft tall and the lantern is 134ft above sea level. The Low Light was discontinued in 1883; the pair formed leading lights marking safe passage around the southern end of the treacherous Haisborogh Sands. http://www.happisburgh.org/content/view/19/29/ - http://www.happisburgh.org/content/view/12/26/
