5-min walk from Cordoba's main square is the Templo Romano, the ruins of Roman temple dating back to the 1st century A.D during the reign of the Emperor Domitian (81-96 CE). The ruins are badly degraded and the columns have been reconstructed, but at night the place is nicely lit up. A family of feral cats at the site attracts as much attention as the ruins themselves. The Templo Romano, Puente Romano and fragments at the Archaeological Museum are all that remain of Cordoba's Roman past. Free.
