The monument includes a bowl barrow and a superimposed World War II pill box
with associated trenches. It is situated immediately to the south east of
what was formerly Martlesham Heath Airfield. The barrow is visible as an
earthen mound which survives to a maximum height of 1.7m. The mound is now
incomplete, but is known originally to have covered an area approximately 17m
in diameter. On it is a hexagonal pill box, constructed of brick and concrete
and occupying an area of approximately 10 square metres, and around this are
the remains of a gun emplacement and slit trenches with brick retaining walls.
A survey and limited excavation were carried out on the site in July 1991,
in order to ascertain the extent of surviving archaeological deposits in the
barrow. This showed that the mound survives to a height of approximately
0.9m beneath the floor of the pill box and that, even in areas which have
been substantially levelled, parts of the base of the mound and underlying
soils remain intact. One sherd of Bronze Age pottery was found in the yellow
sand of which the mound is composed.
