It has been used since the beginning of the time, more specifically the Stone Age where people used it as a symbol to represent an icon which meant ”last for long time”, also for weapons and almost everything. It was frequently used in important buildings like churches, castles and courthouses. It isn’t all good for stone, it has many disadvantages too, like its transportation, its weight, is very hard to cut and shape, its cost and it isn’t very resistant in front of tension. <span style="color: black; font-family: "Calibri","sans-serif"; font-size: 14pt;"> <span style="color: black; font-family: "Calibri","sans-serif"; font-size: 14pt;">There are two ways to work with stone, the first one is rubble technique that consists in using broken stones and bound them with a mortar, and the second one is the ashlar masonry technique that consists in using blocks of stone regularly cut <span style="color: black; font-family: "Calibri","sans-serif"; font-size: 14pt;">.
