History of
The Wells Cathedral clock has a rich history spanning over 600 years. It was first mentioned in the 14th century, with a payment made for the keeper of the clock in 1392-1393.
The clock's construction is closely tied to Bishop Ralph Erghum, who moved from Salisbury to Wells in 1388. He had previously installed a clock in Salisbury in 1386, and it's possible that he brought his clockmakers with him to Wells.

The Wells clock shows some improvements and additions compared to the Salisbury clock, suggesting that valuable lessons were learned. The Wells striking system uses a double lever, which is more reliable than the system used in Salisbury.
The clock was converted to pendulum and anchor escapement in the 17th century. The original mechanism was installed in the Science Museum in London in 1884, where it's still wound by hand for visitors today.
The tradition of winding the clock by hand was upheld for centuries, with the Keeper of the Great Clock winding the clock three times a week. This process took over two hours and required cranking the 250kg weights 800 times with an iron key.
The Keeper of the Great Clock was a significant position, with the Fisher family holding the role for almost 100 years since 1919. Paul Fisher was the last Keeper to retire in 2010, marking the end of an era.
