Big Ben - Elizabeth Tower - London, UK

The Elizabeth Tower is the clock tower of the Palace of Westminster in London, England. It contains the Great Clock, a striking clock with five bells. The tower is nicknamed "Big Ben", a name which was originally applied only to the largest bell of the clock. The tower was officially called the Clock Tower until 2012, when it was renamed to mark the Diamond Jubilee of Elizabeth II. The "Big Ben", was built as a part of Charles Barry's design for a new Palace of Westminster after the old palace was largely destroyed by fire on 16 October 1834. Although Barry was the chief architect of the neo-gothic palace, he turned to Augustus Pugin for the design of the Clock Tower, which resembles earlier Pugin designs, including one for Scarisbrick Hall in Lancashire. Construction of the tower began on 28 September 1843. The building contractors were Thomas Grissell and Morton Peto.
