History
Foundation of Smila
Smila and its neighbourhood have been settled since the ancient times. Archeologists discovered a number of ruins of ancient settlements and numerous mounds located in different parts of Smila and near the city. Two biggest ancient settlements and 44 mounds were first researched during 1879–1883 years by O. O. Bobrynsky, grandson of Smila owner, Count Olexiy Olexiyovich Bobrynsky. These findings belong partly to the Stone Age and partly to the Bronze Age. Official foundation date of Smila is 1542. Grand Duchy of Lithuania documents tell us that settlement Yatzkove-Tyasmyno was founded on a hamlet place in 1542. The modern name of the city has been known since the first half of the 17th century. City's name is connected with a local legend first recorded by Count L. O. Bobrynsky: "An unknown girl led warriors through a heavy swamp showing a route to the enemy. The battle was very bloody. They killed a lot of enemies there but they couldn’t save the brave girl. They buried her near Tyasmyn and called her Smila. Then warriors honoured her in the city’s name."
