Due to the new reservoirs built in the '50s and '60s, many villages and towns were abandoned and flooded. Granadilla was high above the new reservoir but was effectively surrounded by it and cut off from its farmlands (please have a look at the aerial map to get a gist of this isolation). The population moved to the cities in the main. Some decades later as the place became something of a tourist attraction, a few souls moved in to open a restaurant or two and some tourist shops. I've posted a couple of other shots under my Estramadura album: www.ipernity.com/doc/2247598/album/999420

I thought of 'When the levee breaks', a great blues song for this, even if it's not strictly relevant to the photo. www.youtube.com/watch?v=BYThZwcDUXk
I selected a 'reaction' Youtube version of this Led Zeppelin classic, just because it was an honest and sincere reaction and it amused me!
