Station at St. Peter's Chains
(S. Pietro in Vincoli)
built by the Empress Eudocia Licinia in 442,
during the pontificate of
St. Leo the Great.
She here placed the chain with which
St. Peter had been bound in prison in Jerusalem,
brought from the East by her mother Eudoxia Athenais.
Another chain of the Apostle was already venerated in Rome,
that with which he had been fettered in the Marmertine prison.
St. Leo the Great united the two,
forming one continuous chain about two yards long.
In the fifth century this basilica was one of the twenty-five parishes of Rome.
