The Fortress of Bashtovë is a medieval quadrangular fortress located on a fertile flat ground east of the mouth of the Shkumbin River.
Previously in the Middle Ages, the region of Boshtovë was known as a trade harbor and otherwise centre for the export of grains. The origin of the fortress has been for some time a matter of dispute among historians. The initial fortress was constructed during the time when the region was part of the Venetian Empire as according to Gjerak Karaiskaj. However, Alain Ducellier has asserted that the Venetians have built over an existing former structure, which dates back to the 6th century, when the area was under the Byzantine Empire during the Justinian dynasty.
The fortress is a rectangular structure oriented to the north-south direction. There are three entrances, from which there still are well-preserved archaeological traces they were placed at the northern, western and eastern walls. The walls are 9 metres high and comprise a roughly 60 by 90 metres interior. In the north and east, there stands round towers each of them 12 metres high.
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.
