London's most popular new attraction, this massive Ferris wheel stands at 135m high and towers over Big Ben across the river. Has won the hearts of Londoners, who are turning up in droves to have a ride. A labyrinth of 21 spartan rooms, which have been kept virtually untouched since their glory days in the 1940s. This magnificent ship is the last surviving tea clipper, beautifully restored, with a fine collection of carved figureheads. This is Charles DIckens' only surviving London house, home to a huge collection of manuscripts, paintings, personal items and memorabilia.
Visitors can explore all nine decks.
There has been a prison on this site since 1616, and this underground warren of cells extending deep under Clerkenwell is a genuinely grim, drippy place to visit. It's also reputed to be haunted. The Palace of Westminster has been home to the House of Commons and the House of Lords since 1547. This neo-Gothic building, with its hundreds of delicate finials, replaced the original which burnt down in 1834. It's possible to view both Houses in session from the Strangers' Galleries.
