Berlanga de Duero Castle, which is now in ruins, dates back to the 15th century though it was built over a 10th-century Muslim fortress of which there are no remnants. It originally belonged to the Tovar family who ordered the construction of the village’s collegiate. This castle played an important role, along with the defensive wall, in defending the villages along the Douro riverbanks during the Muslim Conquest. Of the remains that are left of the castle, it is worth noting the keep which is in very good condition.
References:Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
