Big Ben is Britain's most popular tourist attraction

The tower's original name is "Clock Tower", the name given to the giant bell inside the Big Ben tower. It is officially known as the "Big Bell".
Big Ben is the largest tower of the Palace of Westminster in London. In September 2012, the tower was renamed the Elizabeth Tower to commemorate the 60th anniversary of Queen Elizabeth II's accession to the throne.
As of 2008, Big Ben is the most popular tourist attraction in the United Kingdom.
The Clock Tower is sometimes erroneously referred to as Stephen's Tower. Stephen's Tower was found on the western side of the parliament building and was the public entrance.
According to reports, Big Ben first rang on May 31, 1859.
On the top of the clock there is an inscription "Domine Salvam Fac Reginam Nostrum Victoriam Primam" in Latin. It means: "Lord, protect Queen Victoria I".
The original sources for the name Big Ben are unreliable. Some say the tower is named after Benjamin Hall, a famous politician, while others say it was named after Benjamin Count, a tournament winner, when the tower was built.
Big Ben sounds every 15 minutes and can be heard within a radius of up to 5 miles.
