The Basilica of Vera Cruz consists of two clearly differentiated parts: the walls and the sanctuary. Despite its Islamic origins, the monument has undergone many changes. Nowadays, 14 different shaped-and-sized fortified towers are spread along the wall. The fortress belonged first to the Order of the Temple, and later to the Order of Santiago, a Spanish Christian military order. Moreover, the castle was used for military purposes during the Spanish Succession War and the Peninsular War.
The Holy True Cross Sanctuary was built in the heart of the old fortress in the 17th century. Then, in the 18th century, its magnificent baroque façade was annexed to the sanctuary. The church has a Latin-Cross plan, a continuous gallery over the lateral naves, and also a dome over the transept. Recently, the Holy True Cross Museum has been reopened in the sanctuary rooms.
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.
