Ashlar stones are used in building construction both in connection with mortar in the masonry bond and as dry masonry . In contrast to masonry bricks, each stone must be prepared by the stonemason . In order to limit this effort, they are given a much larger format than the brick. On the other hand, with these large stones it is easier to achieve the monumental effect of the building , which is often desired . That is why they were mainly used in sacred buildings , but also in palaces and castles , here also because of their special strength. The pyramids were already built with ashlar stones.
