The common stones used for masonry construction are tuff stone, gneiss, limestone, sandstone, granite, marble, andesite, basalt, etc.

To build an arch, you start with two low wall sections of equal height on either side of a gap that's the planned width of the arch.

Keystone. The keystone is the most vital piece of the stone arch. It's the wedge-shaped piece that is located at the very apex of the arch.
