Reasons for Designation
Long mortuary enclosures are oblong-shaped enclosures up to 150m in length,
surrounded by narrow, fairly straight ditches with slightly rounded corners,
containing an open space edged by a perimeter bank set within the ditch.
Characteristically there are two or more major causeways across the ditch
which served as entrances. Most long mortuary enclosures are orientated
within 45 degrees of an east-west alignment. Long mortuary enclosures are
generally associated with human burials dated to the Early and Middle
Neolithic periods (c.3200-2500 BC). There are approximately 35 examples
recorded in England. The greatest concentration lies in Essex and Suffolk,
but there are also examples along the Thames and in Warwickshire along the
Avon; two isolated examples have been recorded in Northumberland. Long
mortuary enclosures are very rare nationally and all surviving examples are
considered worthy of protection.
Details
The monument includes the buried remains of a long mortuary enclosure of the
Neolithic period and two Bronze Age bowl barrows situated on the eastern side
of the steeply sloping valley of the Otby Beck, immediately north of Otby Top
Farm. The intervening ground between the mortuary enclosure and the barrows,
which is thought to contain archaeological evidence for activities focussed on
the site, is also included in the scheduling.
Although the internal bank of the long mortuary enclosure and the mounds of
the barrows have been reduced by ploughing, their infilled and buried ditches
are visible from the air as a series of cropmarks. The cropmarks (areas of
enhanced growth resulting from higher levels of moisture retained by the
underlying archaeological features) have been recorded on aerial photographs
since 1970.
The long mortuary enclosure is oblong in plan, defined by a straight sided
ditch with slightly rounded corners, measuring some 70m by 40m overall.
Material quarried from this ditch would have been used to construct an
internal perimeter bank, thus further demarking the area set aside for
funerary activities which are thought to have included exposure of the newly
dead and the storage of human remains prior to burial in long barrows. Access
to this ritual compound was provided by a causeway across the north western
arm of the ditch, and a further causeway is thought to exist on the opposing
side. The aerial evidence has not, to date, revealed indications of internal
structures but excavations of similar sites elsewhere in Britain suggest that
pits and post holes may survive beneath the present ground surface. A
further, significant feature which may also be preserved is a paved area or
platform thought to have been used for the deposition and excarnation of the
dead.
Two bowl barrows lie to the north and east of the mortuary enclosure separated
from it by distances of 30m and 10m respectively, and by 40m from each other.
They indicate the location's continuing ritual significance at a later date.
Both barrow mounds have been reduced by ploughing but their encircling quarry
ditches, each measuring approximately 20m in diameter, survive as infilled and
buried features.
The long mortuary enclosure lies within 2km of four Neolithic long barrows
(all the subject of separate scheduling), two to the north and two to the
south. It may thus have served the funerary needs of several communities whose
burial mounds are associated with the valleys of the Otby and Waithe Becks and
with the prehistoric trackway now formalised as High Street (the B1225) which
lies some 550m to the east of the monument.
