Located in the central part of the excavated area, during investigations associated with the construction of the Ramsgate Harbour Approach road in 1997/1998 was a series of three, possibly four or five, concentric arcs of discontinuous groups of cut features. These features were understood to represent part of a ‘causewayed enclosure’ of Early Neolithic Date. Only the southern and northern parts of the Middle Arc were visible in the excavation area, the presumed connecting section lying to the west; there was no sign of this on aerial photographs. The overall length of this reconstructed arc would have been in excess of 180m. Seven segments were recorded relating to this arc, two to the south and five to the north; like the Inner Arc, these were quite shallow, rarely exceeding 0.3m in depth.
