Veleia was a Roman town in Hispania. It was an important station on the Roman road ab Asturica Burdigalam that ran parallel to the coast of the Bay of Biscay. At its apogee, the city could have been inhabited by some five to ten thousand people, and apparently went through different cycles of prosperity and decline into the Early Middle Ages until it was finally abandoned.
The archaeological site of Iruña-Veleia is the most important from the Roman period in the Basque Country. It was alleged to contain the oldest known texts written in the Basque language as well as, allegedly, the oldest representation of the crucifixion of Jesus found to date, but later it was said that the findings were forgeries. Other authors favored their genuinely ancient provenance, in agreement with the stratigraphic dating performed by the archaeologists who made the discoveries.
The town was founded in the 8th century BC, in the Late Bronze Age. The houses from this period, rectangular and round with adobe walls and thatched roofs, are similar to those found at the nearby site of Atxa (Vitoria).
In the first half of the 1st century some of these houses were replaced by others of Roman style (domus). This architectural romanization continued as the century advanced.
The late Roman city (3rd and 4th centuries) is better known. It shows signs of decay and the construction of a wall that encloses an eleven hectare area. The town survived into the 5th century after Roman power had disappeared from the region, but by the end of the century only burial plots in abandoned buildings are found.
There was an abbey at the site at least since the 16th century whose buildings remained visible until the mid 19th century.
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.
