Wheel castle dominates, from his situation in the high part of the escarpe, both the population and the broker of the vale of the Landmark in his extension towards the Ebro. His existence dates of the year 882, when it was conquered by the emir of Cordova from Banu Casi of Saragossa.

His housings are located sheltered by the ravine, on the banks of the river Landmark, which walls turn out to be perforated for numerous caves and wine vaults. It preserves showy noble houses, belonging the majority a XVIIth century and of Renaissance style Aragonese.

The castle is of Moslem origin. Of him there survive diverse traces, of which it stands out the one that was a tower of the homage. Her parochial church of Santa Ann is of Mudejar Gothic style.

In his surroundings, it is possible to visit the place of the Eyes of Pontil, a spring formed by a set of "eyes" from which water runs thermal, going so far as to reach a temperature of 22,4th C. The origin seems to be the laundering of limestones attached to the saw of Plain mountains High, where the rainwater infiltrates into the water table, to more than hundred meters deep, to arise in the Eyes of Pontil, across the breaks of the layers of limestone.
