(Collecta: S. Clemente)
From the Churches of Rome wiki:
The first church here was built by Pope Siricius in the 4th century, close to the Via Labicana catacombs. A hospice which became a centre for pilgrims was located here.
It was restored by Pope Gregory III in the 8th century.
The relics of the martyrs Marcellinus and Peter were brought to the church in 1256, and the church was restored the same years on order from Pope Alexander IV. Twenty years later, the hospice and church were given to the Confraternity of those Commended to the Saviour.
The present church is the result of Pope Benedict XIV's rebuilding in 1751.
