Krevo Castle is one of the oldest Belarus castles and dates from the early 14th century. It is an important place in Belarus because it was the first all-stone castle to be built in the region. The stone walls were 2.5m thick and 13m high. The castle had two towers which guarded the rest of the fortress. Grand Duke Keistut was murdered in the castle in 1381, and in 1385 the famousKrevo Union (between Poland and the Grand Duchy of Lithuania) was signed here.
During the 16th century the Tatars and the Russians tried to capture the castle but it remained intact. By the early 19th century the castle was abandoned and the buildings were mostly destroyed during World War I. Today only the ruins of the castle remain. The perimeter walls can still be seen, but only a few fragments of the towers are still intact. There is a magnificent view of the ruins from the top of nearby Yuryeva Mountain.
Many legends surround the Krevo Castle ruins, including tales of an underground tunnel from the castle to Vilnius, and a beautiful princess who was bricked up alive in the castle walls. There is a pagan temple on Yuryeva Mountain and 1 of 4 amulet boulders, which used to lie at the entrance of Krevo to protect the town against trouble and disease, still remains.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.
