The village of El Barco de Avila is situated in the foothills of the Sierra de Gredos mountain range. After the conquest of Toledo and the retreat of the Muslim lines to the south bank of the river Tajo, King Alfonso VI donated this valley to his daughter and ordered his son-in-law Ramon de Borgoña to erect a fortification and to repopulate the surrounding area.
There is few documented data of the construction of the present castle but due to its architectural design it is dated to the end of the 15th century. The castle, built of granite rubblework, is situated on a small hill on the east bank of the Tormes river. Its groundplan, similar to that of other castles on the Castilian plateau, is a square with circular towers on the corners and sentry boxes in three of its curtain walls. The fourth curtain wall contains the rectangular keep.
The entrance to the keep is on a higher floor level, facing the courtyard. Although totally dismantled you can see traces of two floor levels and columns around a central patio in the walls and floor of the courtyard. Also underground rooms and rain tanks exist beneath the courtyard.
The territory of Valdecorneja is linked to the Alba family since the 14th century when King Enrique II de Trastámara donated it to Don Garci Alvarez de Toledo. It is probably one of the descendants of this first Lord of Valdecorneja who built the present castle.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
