Mola Castle was built during the Arabian period in the 9th century and enlarged in the 10th century by Almohad reign. It was restored by the Kingdom of Valencia in the 14th century. Today there are impressive ruins and the Gaudi-inspired church of Santuario Santa Magdalena.
The church was designed by an engineer from Novelda, José Sala Sala. The work was started in 1918, but was first completed in 1946. It is inspired by the famous La Familia Sagrada, Gaudi's masterpiece in Barcelona, but has several characteristics that make it unique.
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.
