At the selo of Yazhelbitsy the Polomet makes a turn, crosses into Krestetsky District, returns to Valdaysky District, and crosses into Demyansky District.
It is probably most famous as the site of the 1456 Treaty of Yazhelbitsy between Grand Prince Vasily II (r. 1425-1462) and Novgorod the Great, in which Novgorod's political independence was strictly curtailed.
