Church of St Mary and All Saints, Chesterfield

Predominantly dating back to the 14th century, the church is a Grade I listed building and is most known for its twisted spire, an architectural phenomenon which has led to the church being given the common byname of the Crooked Spire. The largest church in Derbyshire, it lies within the Diocese of Derby, in which it forms part of the Archdeaconry of Chesterfield.
The spire was added to the 14th century tower in about 1362. It is both twisted and leaning, twisting 45 degrees and leaning 9 feet 6 inches (2.90 m) from its true centre. The leaning characteristic was initially suspected to be the result of the absence of skilled craftsmen (following the Black Death).

It is now believed that the twisting of the spire was caused by the lead that covers the spire, which was added 300 years after it was built – before this it was covered with oak tiles.[citation needed] The lead causes this twisting phenomenon, because when the sun shines during the day the south side of the tower heats up, causing the lead there to expand at a greater rate than that of the north side of the tower, resulting in unequal expansion and contraction. This was compounded by the weight of the lead (approx. 33 tons) which the spire's bracing was not originally designed to bear.
