Tower Bridge, one of the capital's most iconic buildings, has unveiled a new attraction.
Visitors with a head for heights can walk 'on air' across the river on a new, £1 million, 11-metre long, 1.8-metre wide glass walkway.
With the traffic, tiny pedestrians and water some 42m below your feet, the walkway offers visitors an exciting new perspective on London.

Cost: adults: £7.65, children (5-15) £3.40. Book online at towerbridge.org.uk.
