Torre de Montroi

Spain, Spain

---

Torre de Montroi is a 12th-century Islamic watchtower and remnant of an ancient castle located on a hilltop in Montroi, a small municipality near Valencia, Spain, dominating the Alcalans valley.

Constructed using the tapia (rammed earth) technique with four thick walls forming two rooms per floor across originally four stories, it includes a ground-level cistern, food storage vaults, and a steep internal L-shaped staircase, functioning as both a defensive shelter and signal point linked to nearby castles like Montserrat and Alcalà. 

Part of Valencia's historic Arab defensive belt against invasions, the weathered tower preserves arcades and structural holes for wooden supports, standing today as a cultural landmark amid agricultural landscapes.
