| One of the earliest examples of Christian architecture and an excellent example of the basilica form, the church known as Old Saint Peter’s, in Rome, Italy, was begun in ad 333 and demolished in the 16th century by order of Pope Julius II to make way for the new Saint Peter’s. Based on the shape of a Latin cross, Old Saint Peter’s had a long nave (central aisle) with a transept (projecting wings) crossing the nave near the front of the church. Roman Emperor Constantine the Great (306-337) commissioned the construction of Old Saint Peter’s as a church and public hall after legalizing the Christian religion. |
