Quarry of Group A (Peninsula Interior)
A bypass of the central path leads the visitor to the interior of the peninsula. Here, visitors can see the mining location of the quarries of group A. Apart from the mining location of the abandoned quarry, the breccias are also visible, namely the waste of the marble processing, which is accumulated in piles. Today, the extent of the Group A quarries is not evident, because when they were abandoned, they were later used as areas for the disposal of breccias, which came from the mining of marble at the quarries of the other two groups.
To remove a piece of marble from the bedrock, the ancient quarry workers used at first hoeing tools with which they opened grooves in order to define the perimeter of the desired part. Then, they used tools cutting the marble, in order to be released from the bedrock and removed. At the cited drawings, the techniques with which they used to cut the marble during the Archaic, Classical and Hellenistic periods, are visible. The first drawing shows the techniques of the archaic period. After the initial drill of holes, small metal pins, which were inserted deeper with hammering ripping the marble, were placed in these openings. The next two drawings present the variation of this technique, during the Classical and Hellenistic period, when wider wedges were used.
