The world's largest maritime museum, free to enter, set in a grand Palladian building in Greenwich
The National Maritime Museum in Greenwich holds the world's largest collection of maritime art, maps, manuscripts and navigational instruments. Housed in a grand Palladian building designed by Inigo Jones and Christopher Wren, the museum covers Britain's relationship with the sea from Tudor exploration to modern ocean science.
The permanent galleries are free and range from Nelson's Trafalgar coat, still bearing the hole from the musket ball that killed him, to interactive displays on climate and polar exploration. Greenwich's UNESCO World Heritage Site surrounds the museum, with the Royal Observatory, Cutty Sark and Greenwich Park all within walking distance.
The museum occupies a complex of 17th and 18th-century buildings at the heart of Greenwich's Maritime UNESCO World Heritage Site. The central block was originally the Royal Hospital School, founded in 1712 to educate the sons of seafarers. When the school relocated to Suffolk in 1933, the buildings were repurposed, and the National Maritime Museum opened to the public in 1937.
The site was expanded in 2011 with the Sammy Ofer Wing, designed by C.F. Moller Architects, which added a glazed entrance hall, temporary exhibition spaces and a rooftop terrace with views across Greenwich Park. The museum forms part of Royal Museums Greenwich, alongside the Royal Observatory, the Queen's House and the Cutty Sark.
The permanent galleries are organised thematically rather than chronologically. The Nelson Gallery centres on Trafalgar and the Admiral's personal effects. The Traders Gallery examines the East India Company and the transatlantic slave trade with unflinching detail. Polar Worlds reconstructs the conditions faced by explorers from John Franklin to Ernest Shackleton, with original sledges, clothing and journals.
For families, the Great Map in the Sammy Ofer Wing is an interactive floor projection that responds to movement, triggering animations about ocean currents, trade routes and marine life. The AHOY! children's gallery, aimed at under-7s, offers hands-on play with miniature ships and cargo. Upstairs, the maritime art collection includes Turner's Battle of Trafalgar and Canaletto's views of the Thames.
The museum sits at the centre of a cluster of attractions that can fill an entire day. The Cutty Sark, the world's last surviving tea clipper, is a 5-minute walk north. Greenwich Park rises behind the museum, and at the top of the hill the Royal Observatory marks the Prime Meridian. The Queen's House, a free gallery of maritime art connected to the museum by colonnades, reopened after restoration and houses the Armada Portrait of Elizabeth I.
Greenwich Market, open daily with a focus on food and craft stalls, is 5 minutes away in the town centre. Thames Clippers run riverboat services from Greenwich Pier to central London in about 30 minutes, making the return journey part of the experience.
The permanent galleries and the Queen's House are free. Temporary exhibitions and planetarium shows at the nearby Royal Observatory are ticketed separately.
Nelson's Trafalgar coat is the museum's most significant object and draws the biggest crowds later in the day. Visit the Nelson Gallery first thing for a quieter experience and a closer look at the artefacts.
Greenwich Park connects the museum to the Royal Observatory on the hilltop. The walk takes about 10 minutes and the views from the top across the Thames to Canary Wharf are outstanding.
Uber Boat by Thames Clippers runs from Greenwich Pier to Westminster, Embankment and other central piers. The 30-minute river journey is scenic and avoids the Tube entirely.
The Queen's House is connected to the museum by colonnades and houses a free gallery of maritime art, including the Armada Portrait. It takes about 30 minutes to see and breaks up a longer museum visit.
The rooftop terrace of the Sammy Ofer Wing has a cafe with views over Greenwich Park and the Observatory. It is less crowded than the restaurants in Greenwich town centre, especially on weekends.
