What is the nickname of the clock tower in London?
The clock tower in London is commonly known as "Big Ben." Big Ben is the name of the bell inside the clock tower, but the nickname is often used to refer to the clock tower itself, which is an iconic symbol of London and the United Kingdom. The tower was completed in 1859 and has become one of the most recognized landmarks in the world. It is located at the north end of the Houses of Parliament in Westminster.

Big Ben is the largest four-faced chiming clock in the world, and its name is actually the nickname for the Great Bell. The tower was designed by Augustus Pugin and built by Charles Barry. It is 316 feet (96 meters) tall and the clock faces are about 23 feet (7 meters) in diameter. Each face of the clock is made of cast iron and has a set of golden hour and minute hands. The clock has a very accurate pendulum-based movement and is known for its reliability. The clock tower is a Grade I listed building, which means it is a building of exceptional interest and has a special architectural or historic significance.
