The Alentejo Province is a region of wide plains to the south of the Tagus River (Rio Tejo, in Portuguese). In the heart of this region, at a distance of 130 km from Lisbon, lies the city of Évora. Due to the well-preserved old town centre, still partially enclosed by mediaeval walls, with its large number of monuments dating from various historical periods, Évora is included in UNESCO's World Heritage list.
