Quarries are set up in mountains. In quarries stones are mined from the mountains that are then refined to stoneblocks by stone masons. The production numbers depend on the expansion level, available population and percentage of minable stone of each mountain.

Hints by experienced players:

Since stone can be mined cheaply, a quarry is profitable if no other deposits (gold, iron, coal) were found in profitable quantities.
