Features of Estonian engineering.
Estonian army engineers built fortifications around the village of Vinski near the Russian border.
According to the fortification plan, the village must be protected by an anti-tank trench, which, for the sake of reliability, it was decided to dig around the village and completely surround it.
In a short time the moat was filled with water and now the village is located on an island. Local residents fear for their safety and do not understand how, in the event of a fall, to get out of the "defense" structure.
