Jalance Castle is a Muslim-origin fortress built in the 11th century, with later Christian modifications. It is situated on a hill above the town of Jalance in the Ayora-Cofrentes Valley. Its history is intertwined with the town's, serving as a defense for the lands and people rather than a feudal stronghold. Archaeological excavations have found ceramic remains from the 11th to the 19th century, indicating long-term habitation.
The castle was a battleground during the Carlist Wars in 1836, defended against the attacks of leader Quílez. Floods in 1864 destroyed its orchards and mills and washed away the stone bridge over the Júcar River, which had also happened in 1740. The walls were restored in the 19th century for civil war protection but later fell into disrepair. Today, efforts are being made to consolidate and preserve it.
The castle has a ten-sided polygonal layout, with walls ending in arrow slits and circular corner towers. It consists of two areas: the upper fortified area and the lower area, originally an Islamic albacar, converted into a parade ground by the Christians.
The upper area is accessed by a staircase leading to a corridor connected to various rooms. These include living quarters, ovens, storage areas, a circular silo, and a rectangular cistern.
Jalance Castle is an ideal spot for adventure sports like 'Rugir Pala' or for enjoying cool summer nights illuminated by the light of the Cofrentes nuclear power plant.
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.
