An ancient quarry was discovered during the work of the Water Supply Corporation between the city of Žeitun and Marsaxlokk Bay in the southeast of Malta.
Because the site is close to the megalithic, centuries-old temple complex of Tas-Sil, an archaeologist from the Cultural Heritage Administration was present to oversee the earthworks. He recognized archaeological finds in large rectangular blocks and notified the superintendent of this. Earthworks were halted while archaeologists unearthed the find.
The stone still had visible tool marks when the quarrying stopped, the stone was in the process of being cut into hewn stone blocks. The sides of the rectangular stones were cut off, but the bottoms were still connected to the rock. Unfortunately, no related items or remains have been found to help date the quarry. Based on the stones that were not completely cut from the rock and the type of quarry, archaeologists believe that it was active in the classical era (5th century BC – 5th century AD).
