One of the many things I love about Spain is the sheer number of fortifications. In the distance or round a bend and up pops a castle, fortress or watchtower.
I live in Jaen province which has more fortifications than any other area in Europe. Almost every town has at least one Moorish remain, some more. This was a fabulous castle (one of many I've seen lately) in Almodovar de Rio just east of Cordoba city.
