Romanesque architecture appeared in Catalonia (Spain) around 1000 AD, and is one of the glories of that region where it is said there are over 2,000 Romanesque buildings, the stars of which are the small, beautiful churches scattered in the rural valleys of the north. Particularly striking are the churches in the narrow Vall de Boi, situated in the Alta Ribagorça region of the high Pyrenees and surrounded by steep mountains. http://www.touristeye.com/Romanesque-Route-in-Catalonia-g-122174
