Tyavzino

thumb|Two possible locations of Tyavzino: Popovka and Smolka (Tõrvala), on a map of Estonia from 1938. Tyavzino (, , ) was a village in Russia, located east of the Narva River near Ivangorod. It was the place where the Treaty of Teusina ending the Russo-Swedish War of 1590–1595 between Russia and Sweden was signed. The village's exact location is uncertain.

== Location == According to Peter von Köppen, Tyavzino was the same village as the later Izvoz (), located by the river Luga. However, according to Finnish linguist J. J. Mikkola (1935), contemporary ( 15th–17th centuries) sources suggest that Tyavzino lay somewhere on the eastern bank of the Narva River closer to Ivangorod instead. He proposes that the village was located near modern Popovka. Former curator of the Narva Museum Jevgeni Krivošejev instead places Tyavzino at the site of the later village of Smolka (), which was destroyed during World War II. Both Popovka and Smolka were part of Estonia between 1920 and 1944 within the wider area of Narvataguse.
