The Wall and the Interpretation Centre Monument · Ágreda, Moncayo, Soria Ágreda's interpretation centre occupies a building on Calle Mezquitas, in what was once the town's Arab quarter, next to the Arab wall. The sections of this wall that once encircled the town today house the centre, which explains the overlapping of Christian, Muslim and Jewish quarters within a single precinct through a route with visual and audiovisual material on the town's history. Admission is free, though a visit requires booking an appointment in advance with the tourist office or the town hall. Photo: Diego Delso (CC BY-SA 4.0) What to see and do in Ágreda
