Castilla y Leon
Castilla y Leon, the land of castles, is a large region that covers most of North Central Spain. It nears Madrid on its southern boundary, neighbours La Rioja and Navarra to the east, and stretches as far as, and includes, Bierzo at its north western edge. Perhaps not surprising then that the heartland of Castilian Spain has nine sub-provinces, the most of any Spanish region, and five classified DOs.
