Two excavation squares (c. 6 sq m; Fig. 1) were opened c. 2 m apart, in places where signs of rock cuttings in the chalk bedrock were discerned when probe trenches were dug by mechanical equipment.


A quarry was discovered in the southern square. It consisted of a shallow square recess (1.8 × 2.0 m, max. depth 0.13 m), whose southern and western sides were only preserved. The bedrock surface was c. 0.2 m lower to the north, while in the east a notch in the bedrock, which had been carved to detach stones from the quarry, was visible. The rock cuttings can not be used to determine the size or number of the stones hewn in the quarry.


Two quarries were identified in the northern square. The negatives of several square stones (average dimensions 0.2 × 0.3 × 0.3 m) that had been quarried were visible in a shallow rock cutting (2.0 × 2.5 m, depth 0.18 m) in the northern part of the square. The remains of steps with severance channels of four elongated stones (max. dimensions 0.3 × 0.3 × 1.8 m) were noted in the southern part of the square; however, the depth of the quarry indicates that other stones were possibly hewn there.
