Farmhouse of la Torre de Flot Monument · Olius, Solsonès, Lleida Image of Olius, not of the place itself. Rectangular farmhouse with outbuildings, built next to an old 1078 defense tower, with a large round-arched portal with wide voussoirs on the south façade and Gothic windows on the north and west faces. Twelfth-century towers like this one were not slender watchtowers but military structures along royal roads that from that century became owners' residences. A Bien Cultural de Interés Nacional (Catalonia's top heritage-protection category). Photo: Isidre blanc ( talk ) (CC BY-SA 3.0) What to see and do in Olius
