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. Seemingly concentric to the Middle Arc, on its western side was another arc of cut segments – the outer arc. Only the northern and southern parts of this arc were visible in the excavation area, the central connecting section of the arc lying to the west, clearly visible on aerial photographs. The Middle and Outer Arcs were separated by a gap of about 11-13m, and the overall reconstructed length of the Outer Arc would have been in excess of 200m. Combining excavation and aerial photographic evidence the arc consisted of 19 segments, of which six were exposed in the excavation area.
