Kočani towers were probably built in the second half of the 17th century, when the city was under Ottoman administration. Impact in construction had oriental architecture.
According to current findings, in Kočani and its immediate surroundings were built three medieval towers, two of which are located in the city, situated on both banks of the Kočani river, while the third is located in the village of Dolni Podlog. Those were bey's residential towers. In fact, those residential towers had defensive position, and one of them was used as a clock tower. It is located near the elementary school 'Rade Kratovce and served to indicate the hours by sound in earlier times.
Constructed of massive walls of stone, they left until nowadays as the signs of the past of Kočani. In 1957, the National Authority for Protection of Monuments put under the Law protection both towers in the city.
The medieval tower, located on the right bank of the river in the downtown area, situated between residential buildings, is dominant in space with its height by 18.5 meters. In 1978 the City Council made a decision for revitalization, after which the tower may be used again.
Unfortunately, the tower on the left side of the river has not been amended and is in poor condition. Currently it has no purpose.
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.
