This defensive mound would have been built by the Saxons, with some sort of wooden enclosure. When the Normans arrived, they favoured the classic construction of a keep on top of the mound, surrounded by a wooden enclosing wall or 'bailey' built in about 1067 AD. The only action it saw was a siege by King Stephen in 1136 when one man was hanged and the fortifications burnt down.

In 1801, a lot of its stonework, its well, and two surrounding ditches were clearly visible . The drawing on the right is based on one made at that time. Note also the big spaces around the church.

Nothing now remains above ground of the castle stones - they have been 'recycled' into buildings in the area. 

However, a back exit from the original bailey gave access to the Barton farm - there is still a flight of stone steps leading down into the fields towards Kersdown Barton which may have had their origins in that exit.

A very limited excavation was carried out in 1968 in a small area in the middle of the football pitch.

The drawing on the left shows the results of a RCHM survey in 1992 showing the earthworks surrounding the motte.

A more recent survey (using magnetometers) done in 2002 over the north end of the site has revealed a number of features which are likely to represent ditches, banks, and ridge-and-furrow ploughing.

The drawing on the right was done by Barbara Keene. It shows an impression of what Bampton's Motte and Bailey might have looked like soon after the Norman invasion.

The modern football pitch has rather levelled things out!
