The monument includes a rectangular moated site with internal fishpond at
Marwell Manor. The moat is well-preserved and partly wet although now
landscaped in parts. The site is orientated north-south and has external
dimensions of 160m north-south and 140m east-west. The area enclosed by the
moat is c.130m by 110m. The moat averages 20m wide and has an external bank
of similar width along the southern arm and at the southern end of the
eastern and western arms. That on the eastern arm continues beyond the
southern limit of the moated site for a further 100m and may represent part of
the park boundary. In the south-west corner of the moat island is a fishpond
30m east-west by 20m north-south.
The site was a major rural manor of the Bishops of Winchester from the mid
10th century to the late 16th century. It had an associated park from at
least 1279 until the 17th century. All modern buildings on the moat island,
in addition to the Manor House and Moat House both listed grade II, are
excluded from the scheduling although the ground beneath them is included.

The site of the monument is shown on the attached map extract.

Reasons for Scheduling

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.

Although a large number of moated sites are known in England, relatively few
survive in Hampshire. This site is particularly important as it survives well
and displays an above average range of features. The importance of the site
is considerably enhanced by the survival, on the moat island, of Marwell
Manor, a listed building which is largely intact, and areas of medieval
parkland surrounding the site with surviving archaeological features including
the park pale. In addition, historical associations link the site with the
Bishops of Winchester from the mid 10th to the late 16th century.
