Reasons for Designation

Around 6,000 moated sites are known in England. They consist of wide ditches, often or seasonally water-filled, partly or completely enclosing one or more islands of dry ground on which stood domestic or religious buildings. In some cases the islands were used for horticulture. The majority of moated sites served as prestigious aristocratic and seigneurial residences with the provision of a moat intended as a status symbol rather than a practical military defence. The peak period during which moated sites were built was between about 1250 and 1350 and by far the greatest concentration lies in central and eastern parts of England. However, moated sites were built throughout the medieval period, are widely scattered throughout England and exhibit a high level of diversity in their forms and sizes. They form a significant class of medieval monument and are important for the understanding of the distribution of wealth and status in the countryside. Many examples provide conditions favourable to the survival of organic remains.

The moated site at Albury Farm is of particular importance because it is relatively wells documented. Having been largely undisturbed by later building in the area the monument also survives well, and as a result the archaeological potential of the site is high for the recovery not only of evidence of the development of the buildings on the moat island but also of the environment in which the monument was sited.

The monument at Albury Farm includes the inner and outer banks and ditches of a medieval moated site together with the area enclosed by the ditches on which buildings are considered likely to have stood. Moated sites are generally seen as the prestigious residences of the Lords of the manor, the moat marking the high status of the occupier but also serving to deter casual raiders and wild animals. Most moated sites were constructed in the period either side of 1300 AD, and historical documents exist which confirm that the manor house of Albury existed in the 13th or 14th century, at which time it was in the hands of the de Passelle family. The earthworks form an inner, square moat within which would have stood the manor house itself, and three sides of an outer moat. The fourth side of the outer moat was formed by the stream, now ducted underground, which formerly flowed from north to south on the western side and which filled both the inner and outer moat with water. Earthen banks, some of impressive proportions, survive both around the edge of the moat island and on the outer edge of the outer moat, although they have been partially slighted at the south-east corner, perhaps at the same time as the house of Albury Manor was demolished around 1750. The tarmac path leading across the southern side of the scheduled area, the benches on the western side and the surrounding fencing are all excluded from the scheduling, although the ground beneath the path and benches remains included.

MAP EXTRACT The site of the monument is shown on the attached map extract. It includes a 2 metre boundary around the archaeological features, considered to be essential for the monument's support and preservation.
