The emblem of the Leszno Community originally comes from the emblem of the nobility of the Leszczyński family from the Mazovia. In the Middle Ages Leszno was owned by the Leszczyński family. Here it was also the place of its residence.
The name "Leszno" as such comes directly from the last name of the family which was written either Leszczyńscy or Lesniewscy. Due to this fact in XVI and XVII century the village was called both Leszno as well as Leśno.
At the navy blue shield there is a silver horseshoe with its ends turned down. At the top you can find a cross, the second one is placed in the center of the horseshoe. For the needs of the emblem of the Leszno Community to the original "Boża Wola" emblem there was added two golden wheatears at the bottom.
These wheatears are the symbol of the assiduity of the farmers from Leszno. Marek Wasilewski prepared the visualisation of the emblem.
The emblem was approved by the Council of the Leszno Community on 29 August 1995 and afterwards it was dedicated by
the Primate Priest Józef Glemp during a mass for the harvest festival in September 1995.
