Trinity House is the official General Lighthouse Authority (GLA) for England, Wales, the Channel Islands, and Gibraltar. Its primary duty is operating and maintaining over 60 lighthouses, lightships, buoys, and other navigational aids that guide ships safely through British waters. The organisation works closely with the Northern Lighthouse Board and the Commissioners of Irish Lights.
The headquarters are in London, and the operational headquarters are in Harwich. In addition, there are regional Trinity House depots around England and Wales to service and maintain aids to navigation, though some of these are no longer in service.

Trinity House, under the Royal Charter granted by King Henry VIII in 1514, was established as a guild for mariners. Its mission was to enhance shipping safety and regulate ship pilotage in the Thames. Over time, its responsibilities expanded to include the management of navigational aids around the British Isles.
Trinity House has a wide range of responsibilities. It has constructed and maintained lighthouses, lightvessels, and buoys around the coast. The corporation is also responsible for inspecting aids to navigation, marking wrecks, and providing other vital services that protect lives at sea.

The Trinity House headquarters at Tower Hill overlooks the Tower of London. The building, which dates back to 1796 and was designed by architect Samuel Wyat, is not only the administrative centre of Trinity House but also a historic landmark.
The beautiful Georgian building has a grand staircase, elegant rooms, and a collection of maritime artefacts. The interior is adorned with paintings, ship models, and other nautical memorabilia that reflect the organisation’s rich history.

The library contains many books, charts, and manuscripts about maritime history and navigation. It is a valuable resource for researchers and historians. The former lens from Les Hanois Lighthouse in Guernsey is displayed close to the reception desk.
The organisation also oversees the licensing and training of maritime pilots, who guide ships into port through complex or congested waters.

Beyond its navigational duties, Trinity House is a charitable organisation. It extends support to retired mariners, their families, and others connected with the sea, which has been an integral part of its mission since its inception.
Guided tours of the headquarters can be arranged, allowing visitors to explore the historic building and learn about its rich maritime history.
