It has been called the "Cathedral of South Cheshire" and it is considered by some to be one of the finest medieval churches, not only in Cheshire, but in the whole of England. The architectural writer Raymond Richards described it as "one of the great architectural treasures of Cheshire", and Alec Clifton-Taylor included it in his list of "outstanding" English parish churches.
