Lida Castle with another tower and two entrances in the southern and eastern walls is at the stage of completion of construction. The castle was built on an embankment sand hill surrounded by the marshy banks of the Lideya and Kamenka rivers. The construction of the Lida Castle (by the way, one of the largest stone castles on the territory of modern Belarus) occurred in the thirties of the XIV century.
Taking advantage of the temporary truce, in the spring of 1323, Gediminas sent letters to the Hanseatic (North German) cities that did not really favor the Crusaders, inviting various artisans, including masons, to work. Some people believe that Hanseatic craftsmen were directly involved in the construction of the Lida Castle. Local builders, together with invited foreign ones, took the knight's castell as a basis, redesigned and adapted it to local natural and protective conditions.
Wooden scaffolding was erected at the construction site. At the same time, horizontal beams were struck into holes made in the walls. Boards were laid crosswise them from top. Currently, there can be seen square depressions on the southern wall of the Castle. These are the marks from the scaffolding. Upon completion, the constructional niches were filled with limestone, but over time it was coming off.
The Castle was built of field stone and brick. Scientist Mikhail Tkachev estimated that about 23 thousand cubic meters of stone, about 1.5 million bricks, a large amount of lime and sand were used. Presumably, the work was carried out for 5-7 years.
