Castell de Tibi in Alicante's Alcoià region originated as a 10th-century fortress under the Almohad dynasty until its conquest by James I of Aragon in 1240. The castle sits upon a distinctive elongated peak, anchoring the strategic defense of the medieval realm. Beyond its military significance, Tibi is notable for housing one of Europe's most ancient water management systems—the Pantano de Tibi reservoir, built to control water flow and delivery across the arid landscape. This combination of formidable medieval architecture and pioneering hydraulic engineering demonstrates the sophisticated planning that characterized castle construction in medieval Iberia.
