A stone Anglo-Saxon church built in about 1040 AD the tower of which still stands today, St Mary's Church is believed to stand on the same site as Guildford’s first church which was probably a small timber structure built in about 600 AD. St Mary's Church tower, which is built of rough flint, is the oldest surviving piece of architecture in Guildford being at least 70 years older than the nearby Guildford Castle. As Guildford was a popular Royal residence in the 12th and 13th Centuries and as St Mary's is very close to Guildford Castle it was used for Royal worship and Thomas Becket may have celebrated Mass here. In about 1120 the Canons of Merton Priory acquired St Mary's and rebuilt the church giving it the cross-shaped plan we see today. In the 1140s the St John’s chapel was added to the south of the church. Much of the present building dates from the 1180s. The chancel had an apse until it was demolished in 1825. In the 14th century a large number of windows were inserted, while the chancel has a 15th-century east window of five cinquefoiled lights with tracery over, in a four-centred head. During the Reformation the church underwent significant changes in the way it was decorated but the corbels mainly survived including one on the South side of a carving of ravens placing food into Elijah’s mouth. Two other corbels in the north aisle, however, which had been carved to show angels still show signs of destruction from that period. Guildford Methodist Church officially joined St Mary's on 1 September 2013, and the church is now a joint Anglican and Methodist congregation as well as being part of a joint parish with nearby Holy Trinity.
Design
In 1825 the chancel was shortened to allow for the adjacent Quarry Street to be widened. In 1862 St Mary’s was restored by Thomas Goodchild when the stonework was renewed and the gallery removed. Goodchild's restoration did not eliminate the 11th- and 12th-century fabric of this ancient parish church. The whole of the exterior of the walling has been encased with flint, and all the buttresses are Victorian except one. The West window of the north aisle is by the Royal Bavarian Art Institute for Stained Glass and dates from about 1850. The font is Victorian and has a square bowl of clunch with scalloped under-edge, resting on a chamfered square stem and four small stone shafts with scalloped capitals and moulded bases. The pulpit, which was added by Goodchild, is of stone and marble and replaced one from the 17th-century.

From the present pulpit the Reverend Charles Lutwidge Dodgson used to occasionally preach when staying with his family in their home, The Chestnuts nearby. It was also at St Mary’s that his funeral was held.
