The eastern end of the church includes fabric from the 12th century, with the Elder Lady Chapel which was added in the early 13th century. Much of the church was rebuilt in the English Decorated Gothic style during the 14th century despite financial problems within the abbey. In the 15th century the transept and central tower were added. The nave was incomplete at the Dissolution of the Monasteries in 1539 and was demolished. In the 19th century Gothic Revival a new nave was built by George Edmund Street partially using the original plans. The western twin towers, designed by John Loughborough Pearson, were completed in 1888.
