The parish church of St Mary in Aylesbury dates from around the start of the 13th century though there is evidence of an earlier church of Saxon origin on the site. Like many churches it has been substantially changed over the following centuries. A lady chapel was added in the 14th century, a clerestory in the 15th. The church was also extended at this time. The tower was topped with a spire in the 17th century.
By the 19th century the church was in a poor state and in need of renovation, it was even feared it was near collapse. Restoration under the guidance of Sir George Gilbert Scott took place in the mid-19th century and the church was given a distinctive Victorian feel.
