With its mix of ancient Greek and naval motifs, the neoclassical Chapel of St Peter and St Paul in the Queen Mary Building at Old Royal Naval College is decorated in an elaborate rococo style with lots of trompe l'oeil details. The eastern end of the chapel is dominated by the Preservation of St Paul after Shipwreck at Malta painting by the 18th-century American artist Benjamin West.
Note the astonishing neoclassical ceiling, decorated in a tantalising and triumphant blend of cream and light blue. The chapel is famed for its excellent acoustics and regularly hosts concerts; check the Old Royal Naval College's website for details. Regular services are also held throughout the week.
