摘要:The active settling of the Upper Posule begins in the first half of the XVII century. One of the fortified settlements, which are being built at that time, was Nedrigayliv castle. After passing it to Moscow side, it was rebuilt and the numbers of people were increasing. Castle had a three-part structure and consisted of small, medium and large cities. During the Northern War Nedrigayliv withstood the siege of the Swedish army. Location in a swampy area affects the preservation of wooden fortifications. The wooden walls finally collapsed and never repaired in the middle of the XVIII century. In 1787 year Nedrigayliv was rebuilt on a new plan, changing its layout.
