Due to the presence of Greek colonies on the Lower Peninsula, the Romans adopted many of the Greek gods as their own. ... While this fusion of Roman and Greek deities influenced Rome in many ways, their religion remained practical. Roman religion absorbed many of the gods and cults of conquered nations.
Rome became the center of the Catholic Church and the capital city of the Papal States; consequently, a great number of churches, convents, and other religious buildings were erected in the city, sometimes above the ruins of older pre-Christian sites of worship.
