Steel-and-concrete fortifications were common during the 19th and early 20th centuries.However the advances in modern warfare since World War I have made large-scale fortifications obsolete in most situations.

Humans have constructed defensive works for many thousands of years, in a variety of increasingly complex designs.The Early Middle Ages saw the creation of some towns built around castles.Medieval-style fortifications were largely made obsolete by the arrival of cannons in the 14th century.Some settlements in the Indus Valley Civilization were the first small cities to be fortified.

In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls).Fortification is usually divided into two branches: permanent fortification and field fortification.
