Castle of Alba de Aliste is located on the margins of the river Aliste. Today it lies in ruins. In the 12th century it belonged to the Knights Templar. Don Álvaro de Luna owned it in the 15th century. It became the capital of the county of Alba y Aliste under Enrique IV.
It was built on the remains of an old Vetton fort in the 12th century and renovated in the 15th century, retaining only some walls and a tower, although it had an irregular plan of 30 meters wide and 70 long, four towers, barbican and crenellated.
References:La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
