A blind guide, the curious case of Picassos barber, chained convicts building a dam, a secret king that ruled at the same time as the real king of Spain, 74 dragons hiding in the ceiling of a church, a wolf hunter, the strangest traffic circle art, a holy wafer that bled... these are only a few of the “hidden” curiosities waiting to be “discovered” by readers of this third part of Hidden Madrid that focuses on the villages in the province of Madrid. Was the true discoverer of the source of the Blue Nile a Spaniard from the little village of Olmeda de las Fuentes? Does the stork in the official coat-of-arms of Las Rozas represent a real stork called María?
