Old St. Peter's
The original church and basilica founded by Constantine in Rome to honor the martyred St. Peter, chief of Jesus' disciples and first high priest of the Christians. The church was begun in AD 313 and was the most significant of the Early Christian basilicas. It was torn down in the early 16th century in order to build the grandiose new structure worked on by Bramante, Raphael, Michelangelo, and others.
