Royal Sovereign lighthouse is a decommissioned lighthouse marking the Royal Sovereign shoal, a sandbank offshore from Eastbourne. The structure's distinctive shape is easily recognised as the lighthouse tower is perched above a large platform (which functions as a helicopter deck) supported by a single pillar rising out of the water. Originally, the platform was manned by three full-time keepers, accommodation being contained in the 'cabin section' immediately below the platform. Additional accommodation was provided for up to four visiting maintenance workers. Read more on Wikipedia
