an arch is a structure that spans a space while supporting weight e.g. a doorway in a stone wall. arches appeared as early as the 2nd millennium bc in mesopotamian brick architecture and their systematic use started with the ancient romans who were the first to apply the technique to a wide range of structures. the ancient romans learned the arch from the etruscans, refined it and were the first builders to tap its full potential for above ground buildings.
