Basilica

A rectangular building plan consisting of a nave terminating in an apse, with aisles on one or more sides separated from the nave by a screen of columns. The building type has its origins in the large public meeting halls and law courts of Republican and Imperial Rome, and was later adopted for the earliest Christian churches. The central nave is often higher than the side aisles, allowing for the insertion of windows known as clerestory windows.
