Introduction
The blocks used to make the castle are of the same carbonate rock that surrounds it and the stonemasons’ marks can still be made out, which has made it possible to locate the main quarries.
You are looking at one of the five quarries located in the area around the castle. Three are situated around the castle and parallel to it. Given their position, it appears that the intention was they would act as a moat once the castle was completed. The other two are located further away. The location of the quarries suggests they were not picked at random, but that they were intended to prevent access by an enemy that never appeared.
