Saint Basilica Stefana (Basilica di Santo Stefano Rotondo) in Rome is a temple from the fifth century. Attention is drawn to the original mosaics, the 15th-century altar - the work of Bernardo Rossellino from Florence, and an extremely valuable monument from the 5th century in the form of the chair of Pope Gregory the Great.
The internal walls are covered with frescoes with 34 scenes of martyrdom, here are torture and executions carried out at the request of Roman emperors. The authors of the paintings were Niccolò Pomaranci and Antonio Tempesty. The underground of the church is occupied by a mithraum from the 2nd century, i.e. a temple dedicated to Mithra, a solar deity (inaccessible to visitors).
Saint Basilica Stephen's is the first Roman church built on a circular plan, during the construction modeled on the Basilica of the Holy Sepulcher in Jerusalem. The building was erected on Celio Hill, a large part of which at that time belonged to the Valerio family (probably it was the founder of the temple).
