San Liberatore a Maiella in Abruzzo, Italy]]In the early Medieval period after the fall of Rome, particularly between the 6th and 11th centuries AD, Romanesque architecture developed, which in large part was influenced by the Basilica design and Roman style of thick outer building walls. The designs were generally simple, symmetrical, with pillars, arcades, and arches. The Basilica style that was initially developed during the Roman period was also sustained, with churches having apses and columned central naves and side aisles.<ref>For more information about the development of Romanesque architecture, see: Fernie, Eric. 1995.
