Open House floats!

Fancy an evening riverboat tour along the Thames to view London's Gherkin and other landmark buildings, in the company of Ken Allinson, author of "London's Contemporary Architecture"? If so, Open House has just such an event for you. It takes place on 19 June, 6.30pm to 8.30pm. A free drink is included in the price of £15. Mercia - the boat shown - leaves from Embankment Pier.
