These Roman ruins may date as far back as the 5th century BC. The best-preserved structures are a Roman theatre and amphitheatre on the fringes of the ancient city, looking out over a valley. Other remains include the outlines of a Visigothic basilica and a section of the aqueduct, which helped keep the city green in what was otherwise a desert. A small museum (included in the price) has some striking exhibits.
The site is near Saelices, 2km south of the A3 motorway between Madrid and Albacete. From Cuenca, drive west 55km on the N400, then turn south on the CM202.
