Contrasts- Tower Bridge and the Walkie Talkie. Tower Bridge, shown here on a fine winter morning, is a much-loved suspension bridge located in the heart of London. This ornate piece of Victorian architecture and sensibility crosses the River Thames close to the Tower of London and has become an iconic symbol of London. Opened in 2015, 20 Fenchurch Street is a commercial skyscraper is located in the historic City of London financial district. It has been nicknamed the Walkie-Talkie' because of its distinctive shape. In contrast to Tower Bridge, its ungainly shape and habit of frying passers-by by reflected sun has led to it being much-derided as a building.
