Lorca

King García Ramírez — the grandson of El Cid — died here in November 1150. The Codex Calixtinus, the 12th-century pilgrim guidebook, warned that the water between here and Estella was poisonous to horses. This was medieval propaganda rather than hydrology — the waters are perfectly safe, and always were. The warning was likely designed to funnel pilgrims toward specific establishments along the route.
