Written records mention the castle in Danków for the first time in the 15th century. According to the descriptions, it was situated on a flat yard which, due to a steadily rising slope located 1.5 km away from the castle itself, lay 30 m higher than the courtyard. A church was constructed in close proximity to the castle, according to some sources as early as in 1550. The church underwent major alterations in the years 1630-1650 and has survived to this day.
Starting from the 17th century, Danków was the seat of the Warszycki family, and it is believed that the first owner was Andrzej Warszycki, Voivode of Podlaskie Voivodeship. The castle underwent major alterations in 1632, when it was governed by Stanislaus III Warszycki; the bastion fortifications were built then. Following the death of Stanislaus III, the Warszycki family kept the castle for a short time, and at the beginning of the 18th century, the estate was taken over by the Pociej family, and then the Wessel family. Due to the loss of its major strategic and defensive importance, starting from 1823, the structure was falling into ruin; its shape of an elongated quadrangle with two gates remained fairly discernible. Nearly 30 years later, no trace was left of the castle structure — the stone walls were dismantled by the locals. One of the unfavourable changes was the formation of another entrance passage in the structure of the west bastion in the 2nd half of the 20th century. The first works aimed at protecting and preserving the site were carried out in the 1970s. Detailed archaeological and architectural research was conducted within the defensive fortifications. The walls were protected with brick siding on the south, west, and east sides (the last being the waterfront).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.
