The Royal Naval College, Greenwich, was a Royal Navy training establishment between 1873 and 1998, providing courses for naval officers. It was the home of the Royal Navy's staff college, which provided advanced training for officers. The equivalent in the British Army was the Staff College, Camberley, and the equivalent in the Royal Air Force was the RAF Staff College, Bracknell.

Greenwich Hospital was a permanent home for retired sailors of the Royal Navy, which operated from 1692 to 1869. Its buildings, in Greenwich, London, were later used by the Royal Naval College, Greenwich and the University of Greenwich, and are now known as the Old Royal Naval College. The word "hospital" was used in its original sense of a place providing hospitality for those in need of it, and did not refer to medical care, although the buildings included an infirmary which, after Greenwich Hospital closed, operated as Dreadnought Seaman's Hospital until 1986. The foundation which operated the hospital still exists, for the benefit of former Royal Navy personnel and their dependants. It now provides sheltered housing on other sites.

Prince Frederick's Barge is a 63.34-foot-long (19.31 m) British state barge. Designed by William Kent, it was built on the South Bank by John Hall for Frederick, Prince of Wales in 1732. Upon Frederick's death in 1751, the barge was used by successive British monarchs until 1849 when she was cut up into three sections and stored in the Royal Barge House at Windsor Great Park. King George VI placed the barge on loan to the National Maritime Museum in 1951, where it is currently on display.

The Old Royal Naval College is the architectural centrepiece of Maritime Greenwich, a World Heritage Site in Greenwich, London, described by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) as being of "outstanding universal value" and reckoned to be the "finest and most dramatically sited architectural and landscape ensemble in the British Isles". The site is managed by the Greenwich Foundation for the Old Royal Naval College, set up in July 1998 as a registered charity to "look after these magnificent buildings and their grounds for the benefit of the nation". The grounds and some of its buildings are open to visitors. The buildings were originally constructed to serve as the Royal Hospital for Seamen at Greenwich, now generally known as Greenwich Hospital, which was designed by Christopher Wren, and built between 1696 and 1712. The hospital closed in 1869. Between 1873 and 1998 it was the Royal Naval College, Greenwich.

St Mary's Church, Greenwich was a church that once stood on King William Walk in central Greenwich in London between 1823 and 1935. As Greenwich's population expanded in the early nineteenth century, there was a need for a second Anglican church in Greenwich to support the existing parish church at St Alfege Church, Greenwich. St Alfege was rebuilt in the 1710s by Nicholas Hawksmoor, but had been the site of a church since the medieval era. St Mary's was located on the edge of Greenwich Park. It was designed by the architect George Basevi in neo-classical style with the construction lasting from 1823 to 1825. There were hints of the style of John Soane, of whom Basevi had been an apprentice. It was demolished in 1935. Its place is now taken by a statue of William IV that was moved there from King William Street in the City of London. The site of the former church now sits on an approach to the National Maritime Museum.

The Baltic Exchange Memorial Glass comprises several stained glass windows designed by English artist John Dudley Forsyth which were installed over a staircase at the Baltic Exchange in London in 1922, as a memorial to the members of the exchange who were killed while serving during the First World War. The memorial glass was damaged in an IRA bombing in 1992. With funding from Swiss Re, the memorial glass was restored by glass conservators Goddard & Gibbs, and has been displayed at the National Maritime Museum in Greenwich since 2005. The memorial forms a hemispherical half-dome about 3 metres (9.8 ft) high, with 240 panels divided into five sectors, with five rectangular windows of painted coloured glass, each of which features a personification of one of the virtues – Truth, Hope, Justice, Fortitude and Faith. The dome is replete with classical and religious symbolism, featuring a winged figure of Victory stepping from a boat into a classical temple, accompanied by Roman soldiers, putti, a dove symbolising peace, the Royal coat of arms of the United Kingdom, and armorial shields and badges for the territories of the British Empire. Two panels, one to either side, list battles in the First World War – Cambrai, Mezières, Arras and Lens, Galipoli, and Messines Ridge to the left; and Bethune, Salonika, Ypres and Loos, Givenchy, Paschendaele to the right. The glass was put together by Lowndes & Drury at The Glass House, Fulham. It was unveiled by General Sir Herbert Alexander Lawrence on 1 June 1922, and dedicated by the Bishop of Willesden William Perrin. It replaced clear glazed windows and dome included on the north side of the exchange when it was rebuilt in 1903. Originally, it was accompanied by marble panels listing the 61 dead, which had been installed earlier and unveiled on 16 July 1920. The glass survived the Second World War intact, but suffered damage in an IRA bombing on 10 April 1992. Only 45 of the 240 panels of the dome were left intact, The other panels, and all five of the windows, suffered damage. Plans to rebuild the Baltic Exchange were abandoned when the extent of the damage became clear. The remnants of the old building were demolished in 1998, and replaced by 30 St Mary Axe (nicknamed the Gherkin) where the glazed rooftop dome refers back to the dome of the Baltic Exchange. The marble panels were installed at the Baltic Exchange's new building at 38 St Mary Axe.

Nelson's Ship in a Bottle is a sculpture by the British-Nigerian artist Yinka Shonibare. Commissioned in 2009 by the Greater London Authority, it was originally placed on the Fourth Plinth in London's Trafalgar Square in 2010. It was subsequently relocated to a plinth outside the Sammy Ofer Wing of the National Maritime Museum in Greenwich, in southeast London, going on permanent display on 23 April 2012, two days before the museum's 75th anniversary. The work was purchased for £362,500 through a joint fund including a £50,000 contribution from the Art Fund and £264,300 from members of the public.
