In 1969 a warehouse at the South end of Ryegate road was demolished prior to the construction of a new Methodist Church. Permission was obtained for four trenches to be excavated to a depth of 2m, located so as not to affect the foundations. This limitation to the area excavated meant that only 'scattered glimpses' of the underlying remains could be obtained. The east (inner) lip of the bailey trench was revealed as was the western edge. Part of the bailey rampart was also excavated and the foundations of a north-south Tudor brick wall were discovered cut into the rampart. The lower levels of the rampart remained intact to a depth of up to 1m. Beneath the rampart was a layer of black humic soil cut by a straight-sided feature which resembled a small robber trench. A mid-eighteenth century rubbish pit was also located. <1>
