Foundation and early years The church foundations date back nine hundred years, being created by
Roger de Beaumont, 2nd Earl of Warwick, in 1123. Between 1370 and 1394, the chancel, transept, nave and aisles were rebuilt, then forming a basilica with wooden roofs. Thomas Beauchamp's descendants built the Chapel of Our Lady, commonly known as the Beauchamp Chapel. It contains the
effigial monuments of
Richard de Beauchamp, 13th Earl of Warwick,
Ambrose Dudley, 3rd Earl of Warwick, and
Robert Dudley, 1st Earl of Leicester. Buried in the chancel of the church is
William Parr, 1st Marquess of Northampton, the brother of queen consort
Catherine Parr.
Sixteenth century onwards The college was dissolved in 1546, and the church was granted by the Crown to the burgesses of Warwick. Sir
Christopher Wren is also said to have contributed to the design, but that is disputed. The church has been undergoing significant maintenance for renovation since early 2023 and is expected to be complete by the end of 2023. At a cost of 1.4 million, the renovation was planned after a piece of masonry fell from the church's tower.{{cite web |last=Smith|first=Kirstie|url=https://www.warwickshireworld.com/news/people/warwicks-iconic-st-marys-church-gets-much-needed-funding-to-help-complete-restoration-work-4029811|title=Warwick's iconic St Mary's Church gets much-needed funding to help complete restoration work
