Two, if memory serves, one a castle and the other a monastery, both of which had been converted to motels. (Although I think if I remember correctly that the monastery did still have some monks living in it.) Couldn't tell you the names to save my life, but then again, Spain is dotted by castles and Roman architecturre, so it could have been one of any dozen cities/villages in the southwestern section of the country, which is what I toured.
