Санта-Мария-ин-Виа-Лата
The church, dedicated to Pope Marcellus I (d. AD 309), is located just inset from Via del Corso, in ancient times called "via Lata", and which now connects Piazza Venezia to Piazza del Popolo. It stands diagonal from the church of Santa Maria in Via Lata and two doors from the Oratory of Santissimo Crocifisso.
