Decumanus.
In Florence, the Decumanus is preserved as the streets Via Strozzi, Via Speziali, and Via del Corso in the city's old centre. Although these streets have different names they form a continuous line with a split between the Via Strozzi and Via Speziali by the Palazzo Strozzi. In Roman times, these three streets formed the Decumanus of Florentina, the name of the Roman colonia. The Via Roma and the Via Calimala are formed from the ancient Cardo, and what was once the Forum in ancient Florence is now the Piazza della Repubblica.
