​  Stone is the first construction material used at the beginning of architecture. It is a natural material extracted from quarries and is composed of minerals. There exist different kinds of stones like quartz or marble, according to the mineral or material which is composed. Stones are very resistant construction material and that is why we use them in construction. The use of stone has several advantages as durability, adaptability to sculptural treatment, and it is used naturally. Another big advantage is that you can find stone everywhere, different kinds with different properties and characteristics. On the other hand, it also has some disadvantages, for example the difficulty to quarry, transport, and to cut it. As another disadvantage we have the weakness in tension. There are two main forms of stonework: rubble (The simplest and cheapest stonework), with broken stone bounded in mortar, and ashlar masonry (the strongest and most suitable stonework) that are regularly cut blocks, for example in the entablature of the ancient Greek temple. Currently the stone remains one of the main building materials, because the stone is part of the concrete mix.
