Originally constructed to serve as the Royal Hospital for Seamen at Greenwich, the Old Royal Naval College, built between 1696 and 1712, is now a UNESCO World Heritage Site. An unforgettable experience, a ceiling tour allows you to marvel at the stunning baroque artwork. Look out for the Franklin Memorial, an impressive marble statue of Sir John Franklin and the crews of the ships Erebus and Terror who died in the ill-fated expedition of 1845 in search of the North West Passage. Spot the naval motifs depicted throughout the chapel or drop by some of the regular choir services still actively held in this place of worship. Be impressed by the Samuel Green organ, famed for the purity of its tone and appreciate one of Britain's most exquisite 18th-century altarpiece painted by Benjamin West.
