Decumanus

In the ancient Roman city of Barcino (present day Barcelona, Spain), the decumanus maximus started at the late-Roman gate (which still stands) in front of the current Plaça Nova square.

[6] In Roman Gadara, present-day Umm Qais, in Jordan, the decumanus runs east–west for approximately one kilometre with its ancient flagstones extant.

[7] Another fine example is the Straight Street or Via Recta in Damascus, which is 1,500 metres long, connecting the eastern and western gates.

In Beirut's central business district, Rue Weygand, which runs east–west, still follows the ancient Roman decumanus.

In Florence, the decumanus is preserved as the streets Via Strozzi, Via Speziali, and Via del Corso in the city's old centre.
