The royal opening of the National Maritime Museum by George VI in 1937 was captured in a series of photographs.
It was opened to the public by King George VI on 27 April 1937. Joining him that day were his wife Queen Elizabeth (the Queen Mother) and their 11-year-old daughter Princess Elizabeth, now Her Majesty the Queen.
The family travelled to Greenwich by river, leaving Westminster Pier on the Admiral's Barge. People had decorated wharves all along the Thames to mark the occasion, and on arrival they were greeted by thousands of local people.
First stop was the Queen's House, which was opened by Queen Elizabeth. Then the King declared the National Maritime Museum open, and the family completed a tour of inspection.
Photographers were on hand to record the event, with a journalist noting that it took the Royal family 20 minutes longer to return to Buckingham Palace by road than it had to arrive by river.
Queen Elizabeth II has maintained her connection to Greenwich ever since. She opened Cutty Sark in 1957 and again in 2012, after her restoration. Her husband, the Duke of Edinburgh, is also a keen supporter.
