The Corporation of Trinity House of Deptford Strond, also known as Trinity House, is the official authority for lighthouses in England, Wales, the Channel Islands and Gibraltar. Trinity House is also responsible for the provision and maintenance of other navigational aids, such as lightvessels, buoys, and maritime radio/satellite communication systems. It is also an official deep sea pilotage authority, providing expert navigators for ships trading in Northern European waters.

Deptford is an area on the south bank of the River Thames in southeast London, in the Royal Borough of Greenwich and London Borough of Lewisham. It is named after a ford of the River Ravensbourne. From the mid 16th century to the late 19th it was home to Deptford Dockyard, the first of the Royal Dockyards. This was a major shipbuilding dock and attracted Peter the Great to come and study shipbuilding. Deptford and the docks are associated with the knighting of Sir Francis Drake by Queen Elizabeth I aboard the Golden Hind, the legend of Sir Walter Raleigh laying down his cape for Elizabeth, Captain James Cook's third voyage aboard HMS Resolution, and the mysterious apparent murder of Christopher Marlowe in a house along Deptford Strand.
