Cáceres has an old walled town in its center. Walk around and you are in the middle ages, given the buildings, the stone streets and total absence of cars. There is a blend of Roman, Moorish, Gothic and Italian Renaissance architecture, not to mention the stork nests. There are thirty towers from the Islamic period still standing.
Humans have inhabited the area since prehistoric times. Evidence of this can be found in the caves of Maltravieso, with cave paintings dating to 25,000 BCE. The city was founded by the Romans in 25 BC and is a Unesco World Heritage Site, quite justifiably so.
Cáceres is in the part of Spain called Extremadura. I always thought that the name Extremadura referred to the extremely hard (dura) quality of the soil and life there but more accurately extremadura is from Latin words meaning literally “outermost hard”, the outermost secure border of an occupied territory. During La Reconquista it was the westernmost holding of the Christians.
