Torre de Doncos

As Nogais, Spain, Spain

---

Torre de Doncos, also known as Fortaleza de Santo Agostiño or Torre da Grupa, is a medieval tower situated on a hill at 614 meters above sea level in Doncos, As Nogais municipality, Lugo province, Galicia, northwestern Spain, strategically positioned along the historic passage from El Bierzo into Galicia near an ancient Roman road.

Constructed in the second half of the 15th century and abandoned by 1603, it features a square keep tower of slate masonry measuring 8 meters per side and 24 meters tall with three floors plus a rock-hewn basement, surrounded by remnants of a defensive quadrangular enclosure with 2-meter-thick walls and a cylindrical turret. 

Associated with noble families like Valcarce, Ayala, and later Fernando de Toledo, it endured devastation during the French invasion and now stands as a protected Bien de Interés Cultural monument, accessible via a mirador viewpoint inaugurated in 2018 amid scenic Ancares landscapes.
