Torrecid, Archaeological remains of a medieval castle in Ateca, Spain.

Torrecid is an archaeological site with the remains of a medieval castle near Ateca, located at about 663 meters in elevation. The visible ruins include foundations of seven rooms and low stone walls, some covered in mud and earth.

Torrecid was a temporary Christian motte-and-bailey camp built by El Cid's men around 1081, during the events the Cantar de Mio Cid places in the Jalón valley. According to the poem, El Cid camped there for fifteen weeks with three hundred knights and three hundred foot soldiers, who pitched their tents around the small fortification. The site stayed buried for almost a thousand years until recent excavations found it where the poem describes it.

The name Torrecid comes from the hill called Cerro Torrecid or Otero del Cid, where El Cid camped for fifteen weeks around 1081 according to the Cantar de Mio Cid. The epic names the site as the otero above Alcocer, and the verses place El Cid's camp beside the Jalón. Visitors can still see the ruins of Alcocer across the river from the hill.

Access is from Ateca via the A-2505 road toward Valtorres; the ruins lie on the right bank of the Jalón, opposite the Alcocer site about two kilometres away. From the low masonry walls you can see Terrer to the right and Ateca to the left. The walls stand barely half a metre high, so watch your footing on the slope.

The site stayed buried for almost a thousand years until excavations found it exactly where the Cantar de Mio Cid places it. Standing on the ruins, a visitor can see the Alcocer remains opposite, Terrer to the right and Ateca to the left, the town that paid parias at the time.
