The history of Leszno dates back to the
Middle Ages. It was mentioned in documents in 1423. It was owned by various families, including the Łuszczewski family, which built a
Baroque palace, which is the main landmark of the village. Several men from Leszno died in various battles against the invading Russians during the
Polish–Soviet War of 1919–1920. A memorial to those soldiers is located in the local Catholic Church of Saint John the Baptist. On September 16, Poles recaptured the village for tactical purposes, while the Germans retreated in panic. Many men were transported to
Błonie, from where they were to be deported to
forced labor to Germany, but some managed to escape. About 70% of the village was burned down. ==Sights==
