Olešnice (German: Oels) is a town in Blansko District in the South Moravian Region in the Czech Republic.

During the colonization of the Bohemian border regions in the mid-13th century, German colonists built new settlement on the east bank opposite the village Olešnice in the area of today's marketplace.

In these times, agricultural production was focused on growing flax and cereals, and eight guilds were established here.

[2] During the Thirty Years' War, Olešnice suffered heavy damage and about 800 inhabitants left the devastated site.

[3] In 1742, during the War of the Austrian Succession, Olešnice was the site of a clash of the largest armies in the area.

This technology has been used here unchanged since 1849 and is included in the UNESCO Intangible Cultural Heritage Lists.

In 1733, the chateau was rebuilt and created a closed complex together with the farm buildings, serving as the office of the Kunštát estate.
