Freemasons’ Hall with its two and half acres of sweeping marbled staircases and ornate hand painted ceilings is one of London’s hidden gems. Situated in Great Queen Street, in the heart of London’s Covent Garden, it is one of the country’s architectural marvels, with a beautiful mosaic ceiling that took over seven years to complete. As well as the home of the United Grand Lodge of England and the Masonic Museum, it is also one of the fifty ‘Unique Venues of London’ and one of the capital’s most-used film locations. Admission to both Freemasons’ Hall and the Museum is FREE. Visit the UGLE website.
