It is the only large Georgian church in Surrey, sporting detailed frescos of the Crucifixion surrounded by the Saints and the Ascended Lord in Heaven, as well as one of the largest unsupported ceilings in southern England.

"buryed in the P'yshe Churche of the Holy Trinitye with in the Town of Guldforde in a Chapell which I have caused to be made for the same iyntent"[4]The Chantry established and funded by Weston is listed in the "Survey of Chantry Lands, Surrey" made between 1546 and 1548 as part of the administering of the Dissolution of the Monasteries as being: "For the mayneteyninge of one priest and one yerely obite for the terme of xx ti (i.e.20) yeares begyninge the xx th day of June in the xxxii yere (1541) of the reigne of our late sovereign lorde Kinge Henry the eight.

[8] Holy Trinity is the only large 18th-century place of worship in Surrey and stands in a commanding position at the top of Guildford's High Street.

The Victorian emphasis on ritual and sacrament called for a larger chancel, and in 1886 the church was enlarged at the east end, creating the present choir, sanctuary, side chapel and organ chamber.

[9] The church is now effectively one huge room with tripartite openings at the east end, allowing access to the chancel and the two side chapels.

The Baroque style baptismal font was given in 1910 by a Miss Russell in memory of her two sisters and has a red marble bowl sitting on a central stem.

It is decorated with the heads of cherubs and acanthus leaves and is possessed of a domed and composite-columned font cover which is currently in storage.

[14] Holy Trinity is Guildford's civic church, where the installation of each new mayor and the town's annual Act of Remembrance is celebrated.
