What types of Christian roman buildings inspired the building of old saint peters basilica?
St Peter’s is built in the Romanesque style, characterized by the arch shape of its windows. It wasn’t inspired by any particularly Christian buildings, but it was inspired by the architecture of ancient Rome; hence the name Romanesque. St. Peter’s does of course have some unique Renaissance touches, and utilizes the principles of perspective which were developed during that period. It is known as a basilica. : ba·sil·i·ca (b-sl-k) n. 1. a. A public building of ancient Rome having a central nave with an apse at one or both ends and two side aisles formed by rows of columns, which was used as a courtroom or assembly hall. b. A Christian church building of a similar design, having a nave with a semicircular apse, two or four side aisles, a narthex, and a clerestory. 2. Roman Catholic Church: A church that has been accorded certain privileges by the pope. http://www.thefreedictionary.
