London is a port city, and Britain became great because of its navy and ability to trade across the globe. The capital’s wealth is built upon that sea trade. There are reminders of London's maritime history everywhere. In Trafalgar Square, we commemorate the 1805 victory (and the death) of Admiral Lord Nelson at the Battle of Trafalgar. At Tower Hill, we remember the 36,000 merchant mariners lost at sea with no known grave. And the Museum of London Docklands examines the triangular trade in goods, sugar and slaves, upon which so much of the city’s wealth was built.

Sandycombe Lodge, the Thames-side villa designed by J. M. W. Turner, has now been re-opened to the public, following a £2.4 million conservation programme. Built in Twickenham in 1813, it was a peaceful retreat for him and he lived there with his father until 1826. Using Turner’s sketches, a William Havell drawing of 1814, architectural evidence and paint analysis, the Turner’s House Trust has returned the house to its original form and decoration as closely as possible.
