A late ancient quarry near Adzba village in middle Egypt datable to the early Byzantine period provides important new evidence for extraction techniques. This paper has tried here to underline the necessity of a proper reconstruction of the process of extracting stone blocks. In general every single block was defined at the quarry face by cutting trenches along the back and sides with a pick following red lines, and split from the bedrock using wedges. The quarry shows the systematic methods used for the extraction of large number of stone blocks in a required size.
