This unusual late-Roman site was discovered in 1983 when an 18-year-old agricultural worker came across a series of beautifully preserved mosaic floors hidden only inches beneath the topsoil. It turned out to be the ruins of a Roman villa – the Casa de Materno – dating from late 4th-century AD. The mosaics, now covered by a large barn, are well-preserved and extensive. Particularly striking is the depiction of the god Oceanus with antennae and a long flowing beard.
The Carranque site also incorporates the foundations of a 4th-century Roman civil building – the Edifico Palacial – which was later turned into a basilica by the Visigoths.
The admission fee includes entrance to a small interpretation centre and museum. Information panels on the site are sketchy. Guided tours (€2 extra) take place on Saturdays around noon.
The village of Carranque is 50km north of Toledo. The site is 6km to the northwest.
