Emsger

Emsger or South Bishop is the largest of the Bishops and Clerks group of islets and rocks, situated west of Ramsey Island, Pembrokeshire, Wales. A lighthouse, designed by James Walker, was built on the island in 1839, acting both as a waymark for vessels navigating offshore and as assistance to ships navigating around the island group. The lighthouse was converted to electric operation in 1959, and in 1971 a helipad was constructed at the site. Finally, the lighthouse was automated and demanned in 1983. Like many in the UK, it is now monitored from the control centre at Trinity House in Harwich, Essex, England.
