Via del Corso
The temple also had a large square arcade surrounded by columns in "giallo antico" and which opened onto the Via Lata (now the Via del Corso) through a triumphal arch. This arch has been identified as the one called the "arch of Antoninus" in later sources, but has also been called the "arch of Claudius" and the "arch of the Tosetti", from the name of the family that inhabited Piazza Sciarra (now disappeared due to road-widening of the Via del Corso). Despite having fallen into ruin and been demolished, the arch still gave its name in the 18th century to the 'Via dell'Archetto'.
