Designed by Wren, the Old Royal Naval College is a magnificent example of monumental classical architecture. Parts are now used by the University of Greenwich and Trinity College of Music, but you can visit the chapel and the extraordinary Painted Hall , which took artist Sir James Thornhill 19 years to complete.
The complex was built on the site of the 15th-century Palace of Placentia, the birthplace of Henry VIII and Elizabeth I. This Tudor connection, along with Greenwich's industrial and maritime history, is explored in the Discover Greenwich centre. The tourist office is based here, along with a cafe/restaurant and microbrewery. Yeomen-led tours of the complex leave at 2pm daily, taking in areas not otherwise open to the public (£6, 90 minutes).
