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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
