Santa Maria in Via Lata is a church on the Via del Corso (the ancient Via Lata). It stands diagonal from the church of St Marcello al Corso.It is claimed that St. Paul spent 2 years here, in the crypt under the church, whilst under house arrest waiting for his trial. This conflicts with the tradition regarding San Paolo alla Regola. The same was also claimed for St Peter, Paul's secretary Luke, Peter's disciple Martial, St John. The first Christian place of worship here was a 5th-century oratory in the Roman building beneath the present church. This was constructed within the remains of a large Roman warehouse, some 250 metres (820 ft) long, which has also been excavated.
