St Mary's Church is the civic church of Bury St Edmunds and is one of the largest parish churches in England. It claims to have the second longest aisle, and the largest West Window of any parish church in the country It was part of the abbey complex and originally was one of three large churches in the town (the others being St James, now St Edmundsbury Cathedral, and St Margaret's, now gone).HistoryThe present church is the second building to stand on the site, the first being built in the 12th century by Mr Hervey. However, nothing survives of the Norman church and the oldest part of the existing building is the decorated chancel (c. 1290). There was a major renovation between the 14th and 16th centuries and it is at this point that the nave, its aisles and the tower were built. It is also at this time that Mary Tudor, favourite sister of Henry VIII, died and was buried in the church. Her tomb is in the sanctuary directly to the north of the Lord's table. The church, however, is dedicated to Mary, the mother of Jesus, and not, as some mistakenly believe, to Mary Tudor.During the 16th century, John Notyngham and Jankyn Smyth, two wealthy local benefactors, died and left large amounts of money to the church. These funds contributed to building the north and south quire aisles, now the Lady Chapel and Suffolk Regimental chapel, two chantry chapels and a north and south porch. The south porch was removed during a restoration in 1830s, and St Wolstan's chapel was added on the north-west side. The interior has been updated with modern utilities since then as well.
