I've just watched two of the thirteen videos in the series, "The 13 Wonders of Spain." It's available for free (with one or two short commercials per episode) on Tubi. I'm not finding these as useful as Rick's videos, but then his videos don't cover quite a few of these places. Getting about twenty minutes of video of a town you're thinking about visiting can be helpful. There's one epsiode on each of the thirteen towns designated UNESCO World Heritage sites:
Alcala de Henares (easily day-trippable from Madrid)
Avila
Caceres
Cordoba
Cuenca
Ibiza
Merida
Salamanca
San Cristobal de la Laguna (Canary Islands)
Santiago de Compostela
Segovia
Tarragona
Toledo
