The National Maritime Museum in Greenwich is the largest museum of its kind anywhere, the centrepiece of a UNESCO World Heritage riverside ensemble that also takes in the Queen's House and the Royal Observatory. Free to enter, it charts Britain's long and complicated relationship with the sea, from exploration and empire to trade, science and naval power.
Why visit
Greenwich is one of London's great days out, and this museum anchors it. The galleries are engaging and child-friendly, the building is magnificent, and it sits steps from the Cutty Sark and a walk uphill from the Royal Observatory.
What to see
Highlights span Nelson and the age of sail, polar exploration, and interactive galleries where children can try their hand at navigation. The neighbouring Queen's House holds a fine art collection, including the famous Armada Portrait.
Visiting tips
The museum is free; the Royal Observatory and its meridian line are ticketed. Reach Greenwich by DLR, train or, best of all, river bus. Set aside most of a day to do Greenwich justice.
