Cave Houses on TV
Some weeks ago, a TV programme about cave houses was broadcasted on TV. It was quite an interesting programme, as not only showed caves and cave houses, but also the way they are built. The report appeared on a programme called "El Escarabajo Verde" (The Green Bettle), on the second Channel of the Spanish TV (Televisión Española).
The programme was about cave houses as a way of living which has been adopted for centuries by people in the High Plateau of Granada (Baza, Guadix, Huéscar, among the most important towns). That´s why I highly recommend you to watch this programme if you have the opportunity, even though you don´t understand Spanish, the images will be something quite new and surprising that you won´t be able to lose it.
You can see the programme in the following web: http://www.rtve.es/alacarta/la2/abecedario/E.html#431973
I hope you like it a lot.
