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.

Be prepared for a large surprise on the Thames River at Nine Elms this September.   What surprise exactly?  Well Dutch artist Florentijn Hofman is preparing his first UK commission.  This will be semi-immersed in the Thames, and will rise and fall with the tide.   Almost certainly it will be large.  Very large.  It is closely under wraps until 2 September, when it will be transported along the Thames, and is likely to be a talking point in the up and coming Vaxhall area.  Hofman is famous for large scaled up sculptures of everyday objects.  Not surprisingly his 26-metre high inflatable “Rubber Duck” has been the focus of much attention in a variety of cities, including Auckland, Sao Paolo and Osaka.
