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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
