[TR 35306956] Salmstone Grange [NR] (1)

Selmstone, Margate was a grange of St. Augustine's Canterbury, with a chapel dated 1326. (See TR 36 NE 65). Other buildings have Early English, Decorated and Perpendicular work while a small vaulted chamber may be 12th c. [See plan after 1936-47 renovations - Archives No.2017, folio 24] (2,3)

Salmestone Grange (name plate ) is an L-shaped, two storeyed building of flint with stone dressings: it has been heavily restored, and is now divided into flats, but it contains many original details. See GP/AO/63/121/5. (4)

Salmestone Grange including chapel (TR 36 NE 65), Nash Road. Grade II*. A monastic grange which once belonged to St Augustine's Canterbury. The north east end of the building was converted into a farmhouse in the C17. This was the Refectory built about 1320. (For full description see list). (5)

Salmestone Grange, Nash Road. Salmestone was one of the most important granges of St Augustine's Abbey. The medieval buildings remain almost complete, if much altered and restored. The only firm date is 1326, the year in which the chapel was consecrated. (See TR 36 NE 65). The hipped roofed building east of the chapel appears to be older as the flints are unknapped; it must have been the hall. The outlines of its large traceried side windows partly remain. Blocked perpendicular doorway at the south end of the west wall. But the structure must be basically early 14th century, and cannot be the new hall, built by Thomas Ickham, Sacristan of St Augustine' Abbey in the 1380s. Of the latter no trace seems to be left. The gabled building that adjoins this cross-ways to the south is the hardest of all to interpret. All the windows have been renewed. The west wall is probably rebuilt and in pale yellow brick. The coping of red tiles here and on all the east gables may not be earlier than the 16th century. Equally enigmatic is the purpose of this building. Beneath its west half, but not extending the full width, is an undercroft with a pointed stone tunnel vault, formed into three bays by transverse ribs. A pointed-headed recess in the two east bays of its south wall - may have been a storage cellar, and the whole building's buttery and pantry? Open to the building through a doorway was the kitchen. The fireplace remains and an oven. The buildings that lay south of the kitchen are ruinous. Remains of a Tudor brick fireplace here. South west of the kitchen is a two storeyed, almost free standing building probably of 13th century date. (6)

Salmstone was a grange and manor, with a chapel and buildings for monks staying there; income as under St Augustines, Canterbury. (7)

TR 353696 Salmstone, Kent, Benedictine. The hall at Salmstone Grange is 14th century. To the east of the hall are the ruins of a chamber or a kitchen. Two useful drawings by Edward Blore (1787-1879) show the chapel and domestic buildings form the north west, the chapel and hall from the south west. To the south-east of the mansion was sited a large thatched tithe barn now totally destroyed (a). (8)

Excavation of foundations in the grounds of the range may represent a west wall contemporary with the undercroft and kitchen, ie. 12th century. (12)

While the Grange itself is medieval, a dig to the south east of the main building revealed foundations, perhaps dating back to the Anglo-Saxon period. See illustration card. (13, 13a)

From the National Heritage List for England:

Details
The monument includes a Benedictine monastic grange situated on the southern edge of modern Margate, around 1.5km inland from the north Thanet coast. The grange survives in the form of standing buildings and associated below ground remains. Historical records suggest that it was founded by the monks of St Augustine's Abbey, Canterbury during the 12th century. The grange operated as the administrative centre for part of their large, mainly arable, estate then covering most of the Isle of Thanet, and as a place of occasional quiet retreat for the monks.

Lying towards the centre of the monument, the standing buildings form an irregular group and include a mainly north east-south west aligned, gabled domestic range and a small, detached, east-west aligned chapel to the west. The domestic range is on two storeys and is faced with rubble, ragstone and flint, with ashlar dressings. Dated by its architectural features mainly to the 13th and early 14th centuries, the range incorporates the original refectory hall, an undercroft with ribbed vaulting, the kitchen and a dormitory wing projecting to the north west. There is also some evidence for earlier, timber-framed walls encased within the later masonry. The range has undergone several phases of alteration and repair, and its north eastern end was converted into a secular farmhouse during the 17th century. By the early 20th century the south western end of the building had fallen into ruin. Surviving in situ medieval features include some original windows and doorways.

The chapel was consecrated in 1326 and may have replaced an earlier, more temporary building. It is mainly faced with knapped flint, with limestone ashlar dressings, topped by a clay tiled, crown post roof. There has been some modern restoration. The modern stained glass windows were completed in 1952. The standing medieval buildings, Listed Grade II*, are in use as a dwelling and working chapel and are therefore excluded from the scheduling, although the ground beneath is included.

Investigations carried out in 1979 revealed evidence for possibly 12th century wall foundations beneath the ruined south western end of the domestic range. Wall footings representing later, now demolished post-medieval buildings were also found in the area immediately north of the main range. Further buried traces of buildings and associated features will survive in the areas between and around the standing buildings. Running within the north eastern edge of the monument is a line of earthworks shown by the 1979 investigations to represent the footings of a row of post-medieval barns and outbuildings. The lower flint courses of a ruined rectangular enclosure situated in the north western corner of the monument are thought to represent a post-medieval barn or animal pound.

After the Dissolution of the Monasteries, Salmestone Grange passed into the ownership of the Crown. Between 1559-1886 it became part of the possessions of the Dean and Chapter of Canterbury Catherdral, before being sold into private ownership.

A number of features are excluded from the scheduling; these are the Grade II* Listed private dwelling and chapel, all associated outbuildings, modern garden features, structures and fences, and the modern surfaces of all paths, tracks, paving and hardstanding; the ground beneath all these features is, however, included.

Reasons for Designation
A monastic grange was a farm owned and run by a monastic community and independent of the secular manorial system of communal agriculture and servile labour. The function of granges was to provide food and raw materials for consumption within the parent monastic house itself, and also to provide surpluses for sale for profit. The first monastic granges appeared in the 12th century but they continued to be constructed and used until the Dissolution. This system of agriculture was pioneered by the Cistercian order but was soon imitated by other orders. Some granges were worked by resident lay-brothers (secular workers) of the order but others were staffed by non-resident labourers. The majority of granges practised a mixed economy but some were specialist in their function. Five types of grange are known: agrarian farms, bercaries (sheep farms), vaccaries (cattle ranches), horse studs and industrial complexes. A monastery might have more than one grange and the wealthiest houses had many. Frequently a grange was established on lands immediately adjacent to the monastery, this being known as the home grange. Other granges, however, could be found wherever the monastic site held lands. On occasion these could be located at some considerable distance from the parent monastery. Granges are broadly comparable with contemporary secular farms although the wealth of the parent house was frequently reflected in the size of the grange and the layout and architectural embellishment of the buildings. Additionally, because of their monastic connection, granges tend to be much better documented than their secular counterparts. No region was without monastic granges. The exact number of sites which originally existed is not precisely known but can be estimated, on the basis of numbers of monastic sites, at several thousand. Of these, however, only a small percentage can be accurately located on the ground today. Of this group of identifiable sites, continued intensive use of many has destroyed much of the evidence of archaeological remains. In view of the importance of granges to medieval rural and monastic life, all sites exhibiting good archaeological survival are identified as nationally important.

Salmestone monastic grange survives well, retaining standing buildings of high architectural quality. Part excavation has confirmed that the monument also contains important archaeological and environmental evidence relating to the original form, use and development of the grange. The monument is one of the best surviving examples of a group of contemporary Benedictine monastic granges which cluster on the Isle of Thanet, illustrating the control exercised over this part of Kent by St Augustine's Abbey at Canterbury during the medieval period.

Historic England archive material (21)

A historic building appraisal of the site in 2020 described the various phases of building work with regard to the layout of the structure. The first phase of building took place in the mid-13th century, comprising a cross-wing structure with a king-strut roof. During the late 13th century, the early structure was encased in masonry, and a stone undercroft was constructed. During the early 14th century the Chapel, Great Chamber, and South Wing were constructed, and a covered walkway to the chapel was built in the mid-14th century. A new Great Hall was constructed by Thomas Ickham during the late 14th century, and a rear West gable of the cross-wing structure with other medieval brick features was constructed during the 15th century. The final phase of building comprised the flooring of Ickham’s hall during the 16th century. Later minor alterations took place between the 17th century and the 20th century. (22)
