💡 Holyhead Mail Pier Lighthouse

Holyhead Mail Pier or Admiralty Pier Lighthouse on Salt Island, Anglesey, is an inactive lighthouse which was designed by the civil engineer John Rennie in 1821. It was built in the early 19th century to help guide shipping into the newly constructed harbour, now known as the Port of Holyhead, which acted as the terminus for the packet service between England and Ireland. It is the last of a series of three lighthouses located on Salt Island.
