Reasons for Designation

Although only part of the original building survives above ground, the remains of the chapel of St Thomas a Becket form an interesting architectural feature within the modern town and provide a valuable indication of the town's medieval origins. The development of the town, which resulted from a deliberate act of colonisation in the late 12th century, is itself of particular interest, and the chapel provides one of most significant clues to the layout of the early settlement. The surviving walls reflect the character of the structure, retaining architectural details which, when compared with the illustrations of the chapel prior to its demise, provide a clear impression of the appearance of the building as a whole. Although the chapel was doubtless robbed for building stone in the late 19th century, the foundations and other buried features are thought to survive and to retain valuable details concerning the construction and evolution of the building. The surrounding enclosure is well attested to by documentary evidence and is also, to some extent, perpetuated by the modern layout of the grounds. Burials recently discovered in this area indicate that the enclosure served as a cemetery, at least from the late 17th century. The presence of burials, a parochial attribute which contradicts the chapel's subsidiary position in relation to South Weald Church, has significant implications for its changing role, perhaps resulting from the demise of monastic control following the Dissolution of the parent abbey in the early 16th century. The cemetery therefore holds the key to understanding the later evolution of the chapel's status within the town, as well as containing a sealed burial population valuable for the demographic study of the town's population during the latter stages of the chapel's use. The chapel enclosure may also retain archaeological evidence for the dramatic events which took place in 1232. The monument is accessible to the public.

The monument includes the standing and buried remains of the Chapel of St Thomas a Becket, located on the south side of Brentwood High Street, some 100m to the east of Crown Street. The chapel was founded in c.1221 by the Augustinian Abbey of St Osyth, near Colchester, and stood within the small town established by the abbey alongside the Colchester to London road. It was intended as a chapel of ease, for the use of the inhabitants of the town and for travellers and pilgrims on the route to Canterbury. However, as a subsidiary chapel to South Weald Church some 2.5km to the north west, it was only permitted to hold divine offices on the dedicatory saint's day and at the time of the charter fair after 1227. The chapel was substantially rebuilt in the 14th century. In this final form, which was illustrated in 1843, the building included a rectangular nave and smaller rectangular chancel, with a tower in the north west corner and a narrow porch on the north side. The building continued in use as a chapel until 1832; thereafter it housed the Boys National School until it was largely dismantled in 1869. The lower part of the tower still stands to the level of the nave roof, retaining the two-centred archways which faced south and east into the nave, and the lower part of a newel stair built into the north west corner. Attached to the tower is the lower part of the west wall of the nave and a short section of the north wall. The low two-centred archways of the north and west doors survive and to the east of the north door is a late 13th century, or early 14th century stoup. The standing walls, which are Listed Grade II, are built of flint and Kentish ragstone with courses of freestone and tile. Limestone was used for quoins and mouldings. The further extent of the nave and chancel is marked by low brick walls built in the 1960s which indicate the positions of the original foundations. In 1232 Henry III caused Hubert de Burgh, Earl of Kent, to be starved into submission when he took sanctuary in the chapel following accusations of treason. During the siege a deep trench was reputedly dug around the chapel and a high fence erected. It is not known whether any archaeological traces of these events survive. The chapel is depicted within a small walled enclosure on a map of the town dated to c.1717, and the north wall of this curtilage is shown in an illustration of the chapel from 1843. The modern garden wall surrounding the remains of the chapel is thought to follow the outline of the enclosure to the south. A set of railings, erected along the western side in 1902, reflects its western boundary and the eastern extent is now covered by a paved walkway beyond the chancel. The northern boundary is marked by a band of dark brick in the refurbished pedestrian area alongside the High Street, during construction of which in 1997 the remains of three adult burials were uncovered. The burials, which dated from the late 17th or early 18th century, overlie earlier graves and are thought to represent the later use of a small cemetery within the enclosure. Since the chapel was originally granted only limited parochial responsibilties, the cemetery may not date back to the foundation. However, the subsequent use of the curtilage for burials provides an important indication of its evolving status. A small rectangular building situated immediately to the north of the tower is of 18th century appearance although it is thought to have originated in the 16th century. The building would have precluded the use of this area for burials and its construction would have disturbed any pre-existing features. The building is not included in the scheduling. A number of features are excluded from the scheduling; these are all modern surfaces and walls, iron gates and railings, seats, litter bins and signposts, the socket for the town's Christmas tree and its metal lid and the modern altar situated within the former chancel, the ground beneath all these features is however included.
