Villavellid Castle is located on a little hill next to the village. By its diposition and characteristics it can be dated to the 15th century and it was probably the residence of a nobleman. Its constructor isn't known although in 1452 a Don Francisco de Almazán, Marquess of Alcañices, was mentioned as the Lord of the village and the owner of a 'strong house'.
Its plan is a square with wide walls of ashlar masonry on the outside. The corners are reinforced by cylindrical towers except one which is reinforced by the square keep which is very reduced at the present time. This all makes the castle in everything very similar to Fuente el Sol Castle. The entrance to the courtyard is by a pointed arced gate, located near the keep. The entrance to the keep is on a higher floor level and would have been accessed by means of a, disappeared, movable wooden footbridge. Inside the tower several wooden floors existed. Also traces of lean-to constructions are observed in the walls around the courtyard.
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.
