In 1669, Lgov Monastery was founded on the spot of the former town, which would be closed down in 1764. The monastic sloboda was transformed into the town of Lgov in 1779.[citation needed]
In 1852 towards the start of his career, Turgenev wrote a chapter in A Sportsman's Sketches entitled Lgov, in which a group of men go hunting in the lake with a pretentious hunter named Vladimir, sink the boat, and then wade to shore filthy after great difficulty.
On September 18, 2022, the town was heavily damaged by a significant F2/T5 tornado. Over 200 structures were damaged or destroyed as a result of this strong wedge tornado. Many residential structures had roofs torn off, and some sustained collapse of their exterior walls, but most of these structures were poorly-built homes. Numerous trees were downed, and high-voltage power lines were also damaged or destroyed.[6][7][8][9][10][11]
In August 2024, at the same time as the Russian authorities declared a "Federal-level" emergency, Lgov was mentioned in an unverified report during the Ukrainian incursion into Kursk.[12]
