8. Cantavieja:
Sitting elegantly at a steep rocky cliff the historic capital of Alto Maestrazgo is not just famous for its amazing architectural heritage but has also been listed as the Property of Cultural Interest. This scenic little town has a complete group of Gothic Aragonese monuments with an Old Castle ruins overlooking it.
Tapered streets with medieval houses create an alluring picture of Cantavieja which is undoubtedly one of the must visit destinations in Spain.
A great list but I would also include some places in Extremadura!
