Royal Museums Greenwich is a group of world-class museums incorporating the National Maritime Museum, Royal Observatory, Cutty Sark and the 17th Century Queen’s House, situated at the heart of the Maritime Greenwich World Heritage Site. The largest and most important museum of its kind in the world, the National Maritime Museum tells the story of Britain and the sea and the importance of the ocean in our lives today, through fascinating artefacts and accounts of discovery and adventure. The Royal Observatory, home of Greenwich Mean Time and the Prime Meridian Line, is one of the most important historic scientific sites in the world. The Cutty Sark relaunched in April 2012, opening a new chapter in the extraordinary life of one of the world’s most famous ships. The Queen’s House, a 17th-century royal house, was begun in 1616 by James I for his queen, Anne of Denmark, and completed in 1638 for Charles I’s French queen, Henrietta Maria, as her so-called ‘house of delights’.
