Erected at the end of the Twelfth century, the Church was entirely re-built in the Fifteenth. The excellent proportions of the exterior are reflected in the interior.

Both the long wagon roof that runs the entire length of the Church and the ancient Parish Chest in the North Transept Chapel are of particular interest, as is the memorial to the first Lord of Ashburton, Lord Dunning, in the South Transept Chapel, penned by his friend the lexicographer Samuel Johnson.

The rebuilding of the church was made possible thanks to the better-off members of the tinners and wool merchant guilds, both of which had Guild Chapels in the transepts, the wool workers in the north transept and the winners in the south.

A massive restoration programme was carried out by the architect W. G. Street in the Nineteenth century to give the Church its present neo-Gothic character.
