Castillo de Vállaga (Ruinas)

Spain, Spain

---

The Castillo de Vállaga comprises ruins of a modest medieval watchtower or small fortress located near the village of the same name in Guadalajara province, Castilla-La Mancha, Spain, dating to the 12th-13th century during the Reconquista frontier defenses.

Constructed from local stone as a simple atalaya-style structure to monitor mountain passes between Sigüenza and the Tajuña valley, it featured basic rectangular walls and lookout slits typical of early Christian repopulation outposts before falling into disuse as borders stabilized.

Today, only scattered foundation remnants and wall fragments survive amid rural fields, accessible by hiking paths and offering insight into Alcarria's sparse defensive network without major restoration efforts.
