National Maritime Museum

More than two million objects, described by the museum and by outside guides alike as the largest maritime collection in the world: paintings, ship models, navigational instruments, charts, manuscripts and uniforms spanning Britain's naval and mercantile history from the Tudor period to the present. It is not a collection built around a single artist or period the way a picture gallery is; it is built around a subject, and the subject is the sea as Britain used it, fought over it and was shaped by it, with the consequences for the countries on the other side of that history given their own galleries rather than left out of the building.

The museum's oldest fabric was not built to hold a collection. The west and east wings and the colonnades that frame the entrance were put up in 1807-1816 by the architect Daniel Alexander as an extension to the Royal Naval Asylum, a charity school for the children of seamen that had recently taken over the Queen's House next door. The school was renamed the Royal Hospital School and stayed on the site until 1933, when it moved out to Holbrook in Suffolk and freed the buildings for a different use.

That different use had already been argued for. In 1927 the Society for Nautical Research launched a public campaign for a national naval and nautical museum, and the name it settled on, the National Maritime Museum, was suggested by the writer Rudyard Kipling, a Society member. The campaign's decisive figure was Sir James Caird, a shipping magnate who bought the A. G. H. Macpherson collection of more than 11,000 maritime prints and ship models and gave it to form the core of the new museum's holdings; the museum's library and archive still carry his name. Parliament passed the National Maritime Museum Act in 1934, establishing a Board of Trustees to hold the collection in trust for the public, and on 27 April 1937 King George VI formally opened the museum, with Princess Elizabeth at his side and Sir Geoffrey Callender as its first director. The museum has occupied a former naval school for longer than the school itself did.

The National Maritime Museum is one of four sites the public body Royal Museums Greenwich runs on and around this stretch of the Thames: this museum, the Queen's House next door, the clipper ship Cutty Sark on the riverfront, and the Royal Observatory Greenwich on the hill above the park. All four sit inside the Maritime Greenwich UNESCO World Heritage Site, and the trust that runs them reports 2,198,914 visits across the group in 2024-25. Entry to the permanent collections of the National Maritime Museum and the Queen's House is free, with no conditions, and the museum only asks that a visitor book a timed slot online to help it manage numbers; the Royal Observatory and Cutty Sark are ticketed, and so is any special exhibition or the Observatory's planetarium.

The price of the ticketed sites moves with the calendar. As of August 2026 the museum's own prices page lists a summer sale running to 2 September 2026: an adult ticket to the Observatory or to Cutty Sark is GBP 18, against a standard price of GBP 24 for the Observatory and GBP 22 for Cutty Sark once the sale ends; a combined Royal Museums Greenwich Day Pass covering both is GBP 30 on sale against a standard GBP 38. Visitors receiving Universal Credit and several other named benefits can buy any ticket, to any site, for a flat GBP 3. None of this touches the museum itself, which stays free before, during and after the sale: the complication belongs entirely to its two ticketed siblings.

Until the late 1990s the space at the centre of the museum's two historic wings was an open service courtyard. Between 1996 and 1999 it was enclosed under a steel and glass roof and reopened as Neptune Court, the museum's largest single development to that date. In 2011 the museum added the Sammy Ofer Wing, named for the shipping magnate whose GBP 20 million gift, announced in 2008, paid for new galleries and public space alongside the historic courtyard. A further refurbishment replaced the courtyard's roof and reworked its ground floor through the early 2020s, finishing in 2025, when the space was renamed once more, from Neptune Court to Ocean Court, and its old walk-on floor map, the Great Map, was itself replaced and renamed the Ocean Map as part of the same refit.

Some of what stands in the court has not changed as often as its name or its floor. Prince Frederick's Barge, a gilded royal ceremonial barge built in 1732 to a design by William Kent for Frederick, Prince of Wales, has been on loan to the museum from King George VI since 1951, and the museum's own current page for the space names the stern of a Trafalgar ship among the returning objects a visitor will still find there: the reconstructed stern of HMS Implacable, a French 74-gun ship built as the Duguay-Trouin in 1800 that fought at Trafalgar under the French flag, escaped the battle, and was captured a month later in the Bay of Biscay. When the Royal Navy finally scuttled the old ship in 1947, the same James Caird who had founded the museum's collection had already paid to have her carved stern cut away and sent to Greenwich; it sat unassembled for fifty years until the Neptune Court project gave it somewhere to hang.

The Atlantic Worlds gallery opened in 2007, timed to the two-hundredth anniversary of the abolition of the British transatlantic slave trade. It sets out the triangular trade, the Middle Passage, and the resistance and abolition movements; the museum's own gallery page names Olaudah Equiano, Mary Prince, Nanny of the Maroons and Sanite Belair among the enslaved and formerly enslaved people who resisted or wrote against the trade, alongside the slave trader John Hawkins and the abolitionist campaigners William Wilberforce and Thomas Clarkson on the other sides of the argument. The museum draws on a Transatlantic Voyages database that records 485 acts of documented resistance by captive Africans aboard slave ships between 1698 and 1807, and states that British ships alone carried 3.4 million African people to the Americas over the trade's history. In its 2024-25 annual report the museum records working with an outside advisory board to update the gallery's content and interpretation again, adding a digital trail on women's roles in resistance and installing the slave voyages database on site; a separate Unlocking Collections project that year generated 250 new catalogue records naming people of colour, drawing on 25 volunteers, across the museum's historic photograph holdings.

Reviewing the gallery on its opening for the trade journal Museums Journal, Caroline Worthington, then director of the Florence Nightingale Museum, praised the museum for confronting the brutality of slavery rather than softening it, but found the gallery's layout gave no clear route through the space and judged that it tried to tell too many stories in one room for any single one to stay with a visitor. From the opposite direction, the historian David Abulafia argued in a January 2024 piece for History Reclaimed and The Spectator that the museum's rework of the neighbouring Nelson, Navy, Nation gallery imports present-day arguments about race onto an 18th-century career, and that Atlantic Worlds gives so much weight to the cruelty of slavery that it leaves too little room for how Britain came to hold its Caribbean territories in the first place. The museum's own Pacific Encounters gallery, on the same floor, raises a related and still more direct question without resolving it: a text panel there states plainly that some people question whether Pacific objects held in European museums, including this one, belong there or should be returned. The museum publishes the question. It does not publish an answer.

Not everything Royal Museums Greenwich holds is inside this building, and the clearest case is also one of the most requested. John Harrison's four marine timekeepers, H1 to H4, the clocks that solved the problem of finding longitude at sea across four decades of Harrison's working life, are displayed at the Royal Observatory Greenwich, on the hill above the park, inside the Time and Longitude gallery, not in the National Maritime Museum building this page describes. H2, H3 and H4 on show there are Harrison's originals; H1, the first and least refined of the four, is currently undergoing conservation at the museum's Prince Philip Maritime Collections Centre, and a full-scale replica, built in 1970, stands at the Observatory in its place while the work continues. A visitor who wants to see the object this archive's Harrison record describes needs a ticket to the Observatory, not to the free museum on Romney Road; the two sites are a steep walk apart inside the same park, and it is the single easiest mistake to make when planning a visit to see them.

We publish no visitor review prose and cite ratings only as a tertiary figure, so what follows is drawn from the museum's own reporting and aggregate platform data. Royal Museums Greenwich recorded 2,198,914 visits in 2024-25 across its sites, and the National Maritime Museum trades on being free where the Observatory and Cutty Sark are not: reviewers consistently single out the free entry to the main museum and the Queen's House as the best-value part of a visit that gets considerably more expensive once a visitor adds the other two sites.
