The National Maritime Museum (NMM) in Greenwich, London, is the world’s largest museum devoted to the history of the sea, ships, and seafaring. Part of the Royal Museums Greenwich—alongside the Royal Observatory, the Queen’s House, and the Cutty Sark—the NMM preserves and presents Britain’s rich maritime heritage, exploring the nation’s deep and enduring relationship with the oceans.
Through its vast collections, interactive galleries, and educational programmes, the museum offers visitors an immersive journey into naval history, exploration, trade, migration, and the global cultural exchanges that have shaped the modern world.
Origins and Foundation
The museum was formally established by the National Maritime Museum Act of 1934, which created the legal framework for a dedicated national museum of maritime history. Its creation reflected Britain’s long-standing identity as a maritime nation, shaped by naval power, global trade, and overseas exploration.
The location chosen for the museum was steeped in naval heritage—Greenwich, historically associated with the Royal Navy and maritime science. Greenwich was home to the Royal Observatory, where the Prime Meridian was defined, and to the Old Royal Naval College, a major naval training centre.
The museum officially opened on 27 April 1937, with King George VI performing the ceremony. From the outset, its mission was to collect, preserve, and display objects and archives connected to Britain’s seafaring past, and to interpret them for the public in an engaging and educational way.
The Building and Setting
The NMM is housed in the former Royal Hospital School building, a grand 19th-century structure designed in the Palladian style. It stands within the Maritime Greenwich UNESCO World Heritage Site, an area recognised for its outstanding universal value in the fields of architecture, science, and history.
The museum’s location near the River Thames is symbolic, reflecting the waterway’s role as the lifeblood of London’s trade and defence. The building’s elegant facades, colonnades, and courtyards provide a stately backdrop to the modern galleries and interactive displays inside.
Collections Overview
The National Maritime Museum holds over two million items, making it one of the most significant maritime collections in the world. Its holdings encompass a wide range of themes, including exploration, navigation, shipbuilding, naval warfare, trade, slavery, migration, and the cultural impact of the sea.
Ship Models and Figureheads
The museum’s ship model collection is internationally renowned, featuring intricate replicas of famous vessels from the 16th century to the present. These models range from working prototypes used by shipbuilders to highly detailed decorative pieces. The figurehead collection, with its carved wooden sculptures once mounted on the prows of ships, reflects the artistry and symbolism of maritime craftsmanship.
Paintings and Maritime Art
The NMM possesses one of the finest collections of maritime art, including works by artists such as J.M.W. Turner, Willem van de Velde the Elder and Younger, and Sir Frank Brangwyn. These paintings capture seascapes, naval battles, and portraits of prominent naval figures.
Navigational Instruments
Reflecting Greenwich’s role in the history of navigation, the museum’s collection of compasses, sextants, chronometers, and other instruments charts the evolution of maritime science. Among its treasures is John Harrison’s marine chronometer H4, a groundbreaking timepiece that solved the problem of calculating longitude at sea.
Maps and Charts
The cartographic collection spans centuries of exploration, including early maps of the New World, Admiralty charts, and globes that reveal how perceptions of the world changed through discovery and colonisation.
Manuscripts and Archives
The NMM houses an extensive archive of ship logs, diaries, letters, and official documents. These records shed light on the lives of sailors, naval officers, traders, and explorers, providing first-hand accounts of life at sea.
Objects of Trade and Empire
The museum’s collections also confront the complex history of Britain’s maritime empire, including objects related to the transatlantic slave trade, colonial encounters, and the exchange of goods and ideas across cultures.
Permanent Galleries
The museum’s galleries are designed to be both informative and immersive, often using multimedia and interactive elements to bring history to life.
Sea Things
An eclectic and visually striking gallery, “Sea Things” displays hundreds of objects from across the collection, from navigational tools to souvenirs brought back by sailors. It invites visitors to reflect on humanity’s relationship with the sea across time.
Nelson, Navy, Nation
This gallery focuses on Britain’s naval dominance from the late 17th to the early 19th centuries, with a central focus on Admiral Lord Nelson and the Battle of Trafalgar. Highlights include Nelson’s personal effects, letters, and the coat he wore when he was mortally wounded in 1805.
Polar Worlds
Exploring the history of Arctic and Antarctic exploration, this gallery examines the challenges faced by polar expeditions, from the voyages of Captain James Cook to Ernest Shackleton’s Endurance expedition. It looks at scientific discovery as well as the human cost of exploration.
Voyagers
This interactive gallery is aimed particularly at families and young visitors, offering hands-on activities that explore navigation, exploration, and maritime technology through the centuries.
Special Exhibitions
The NMM hosts temporary exhibitions that delve into specific themes or periods of maritime history. These have ranged from art-focused displays, such as Turner’s seascapes, to thematic explorations of migration, piracy, women at sea, and contemporary issues like climate change and ocean conservation.
The museum often collaborates with other institutions and international partners, bringing in rare objects from around the world to enhance its exhibitions.
Education and Public Programmes
As part of its mission to educate and inspire, the NMM offers a broad range of learning opportunities:
- School Programmes – Curriculum-linked workshops for all ages, from primary pupils learning about pirates to secondary students studying the slave trade.
- Public Talks and Lectures – Events with historians, curators, and authors discussing maritime history and current maritime issues.
- Family Days – Interactive activities, storytelling, and craft workshops linked to museum themes.
- Research Facilities – The Caird Library and Archive is one of the world’s leading resources for maritime research, open to scholars and the public.
Cultural Significance
The National Maritime Museum is more than a repository of historical objects—it is a place of reflection on Britain’s role in global history. By presenting narratives of exploration, trade, conflict, and migration, it addresses both the achievements and the darker chapters of maritime history, including imperialism and slavery.
As part of the Maritime Greenwich UNESCO World Heritage Site, the NMM contributes to the area’s cultural tourism, drawing millions of visitors each year. Its location alongside the Queen’s House, the Royal Observatory, and the Cutty Sark offers a comprehensive experience of Britain’s seafaring heritage.
The Queen’s House Connection
Next to the NMM stands the Queen’s House, designed by Inigo Jones in the early 17th century. It is an architectural masterpiece and was the first classical building in England. Today, it forms part of the museum’s complex, housing art collections and exhibitions that complement the NMM’s maritime focus.

The National Maritime Museum is free to enter, making it accessible to all. Visitors can explore vast galleries at their own pace, enjoy river views from the museum grounds, or combine their visit with other Greenwich attractions. Facilities include cafés, gift shops, and accessible routes throughout the building.
The museum also embraces digital engagement, offering virtual tours, online exhibitions, and a searchable database of its collections for global audiences.
