Santa Cecilia, music’s patron saint, became martyr here on 230 d. C.. The church, founded before C. V on the place where a Roman house was located, probably Valeriano’s , husband to Santa Cecilia, was redone in obedience to Pope Pasquale I’s will; out of the old construction one saves the apsidal mosaic. 

During C. XII a porch and a bell-tower were annexed. It was continuously restored ever since C. XVI until C.XIX, respectively by the order of Cardinals Francesco Acquaviva and Giacomo Doria Pamphili. The eighteen-century façade is by Fuga and it is preceded by a porch that treasures the antique columns made of pink granite and African marble. 
Not to miss out, inside the nearby convent, the fresco "Il Giudizio universale" by Pietro Cavallini, dated C. XIII.
