A chalk chamber is located 3m to the south of Plumstone road near Acol. This was investigated by Thanet Archaeological Unit in 1984. The work revealed sherds of Romano-British pottery in the infill of the chamber. It was uncertain whether these pottery sherds originally came from the chamber or had accumlated there as a result of slipping through a hole in the chalk. The present locatio of this assemblage is uncertain and it is not known in what condition this monument now exists.
