Villa at Borough Hill

The Borough Hill Roman villa lies within the ramparts of an Iron Age fortress which covers the summit of the hill. Excavations revealed a large range of rooms which ran from north to south, part of which was a bath suite. It was deduced that the northern rooms are later additions. The earliest parts of the villa were built in the early years of the Roman occupation. The villa consisted of a single storey and was constructed from the local marlstone (sandstone), infilled with rubble. The inside walls were plastered, as may have been the exterior, although this is not certain. The building had a tiled roof. Some specimens of frescoed plaster were found still clinging to the remains of interior walls. It was also discovered that the villa had an elaborate heating system installed under the building.
