One of the world’s most famous clocks is returning to service in time to ring in the new year, according to CNN.

Big Ben last bonged regularly on August 21, 2017, before undergoing an intensive, much-needed repair project.

The Cumbria Clock Company, located in England’s Lake District, took on the task of cleaning the clock’s face, chiming mechanism and approximately 1,000 parts over the past four years.

The clock weighs about 5 tons and is 7 feet, 2 inches tall.

While the name Big Ben nowadays refers to the entire clock tower, it is actually the name of the largest bell inside the tower, used to chime the hours.

Big Ben– which is inside Elizabeth Tower in London’s Houses of Parliament — has been keeping time in the UK capital since 1859. This is the single biggest repair project in its history, coming with a price tag of £79.7 million (about $107 million).
