On a slope of soft chalk bedrock and in an area of 8 × 60 m, about 38 rock-cuttings and quarries of the square courtyard type were exposed. One to four layers of quarrying that utilized most of bedrock were discerned in the quarries, as well as severance channels and the negatives of stones that were of uniform size (0.20 ×  0. 35 ×  0.80 m). The work in the quarries was apparently suspended when the quarrymen encountered very hard limestone. The quarries could not be dated due to the absence of ceramic finds.
