The South Bishop Lighthouse is situated on South Bishop Island also known as Emsger, which is approximately 5 miles (8 kilometres) West of St Davids Head, Pembrokeshire, Wales. Designed by James Walker, it 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. This Southerly most island is one of a small group of islands that run behind Ramsey and are collectively known as the Bishops and the Clerks.
Like many in the UK, the South Bishop lighthouse became automated, and unmanned from 1983. It is monitored from the control centre at Trinity House in Harwich.
The Lighthouse was built in the path of migrating sea birds, and due to the brilliance of the light at night, it caused birds to dash themselves against the lantern. Sadly, leading to the deaths of many birds.
This led to Trinity House and the Royal Society for the Protection of Birds teaming up, leading to the conclusion to build special bird perches on the side of the lighthouse lantern. Following this, the amount of deaths decreased considerably.
