Castillo de Tordehumos

Spain, Spain

---

Castillo de Tordehumos consists of 13th-century ruins atop a prominent cerro testigo hill overlooking the Sequillo River valley in Tordehumos, Valladolid province, Castilla y León, Spain, likely built on earlier 10th-century fortifications.

First documented around 1184 under tenente Fernando Moro, it gained fame as the 1194 Treaty of Tordehumos site where Alfonso VIII of Castile and Alfonso IX of León forged peace, with the Orders of Temple and Calatrava guaranteeing terms amid border conflicts.

Recent restorations have stabilized surviving outer walls on its circular platform, creating a panoramic viewpoint of Tierra de Campos plains visible even to the Cantabrian Mountains.
