Church of Santa Maria de Arbas is a good example of late León romanesque, built during the 12th and 13th centuries. It once belonged to the regular order of Saint Agustin. The church has three naves and four pillars supporting the round arches that separate the naves.
It was officially founded in the 12th century by the Count Fruela, El Cid's brother in law.It was ruled as a Colegiata (Collegiate Church) and a Hospedería (Hostelry) by the Augustine monks.As a result of its decline, it became a simple parish church. It was restored after the Civil War. The building consists of fine grey limestone blocks. The gothic chapel was added later, in the 12th century. The sacristy, the tower, the portico and the vaulting of the main nave date from the 17th century.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
