The Arch
Another technological advance was the arch. Sumerian arches were inverted U or V-shaped structures built above doorways. To build arches, Sumerians stacked bricks made of clay and straw so that they rose in steps from walls until they met in the center. Arches added strength and beauty to Sumerian buildings. They became a common feature of temple entrances and upper-class homes. Some historians say the arch is the Sumerian’s greatest architectural achievement.
