The municipality of Olešnice consists of three local parts: Olešnice, Buková and Lhotka.
Similar to several nearby villages, Olešnice is also mentioned in a document from 1186. It used to be a separate estate with a fortress, which was held in the 14th and 15th centuries by the Koňat family from Olešnica, then Zikmund Kebar from Mirošovice and from 1499 the Krajíř family from Krajko.
The oldest building in the village is the fortress, which belonged to the town of České Budějovice from 1727 to May 2001 after a series of owners. Currently, this fortress is owned by the municipality of Olešnice. A parish church was built from the brewery, which was located in the northern wing of the fortress, in 1786 and dedicated to St. Vaclav. The village is dominated by a prismatic tower from the 19th century on the east side of the church. The monument to fallen soldiers - a stone work from 1920 - is also noteworthy.
The noble residence in the middle of the village originally had the character of a fortress, from which a late Gothic stone portal has been preserved to this day.
The cadastral area of Olešnice is 1186 ha. Olešnice itself has 560 permanent residents.
The surrounding rugged terrain consists of the wooded Dubí hill in the southwest and a system of many ponds in the northeast, on the dams of which summer oak and numerous beech stands predominate, and sticky alder in the floodplains of the streams. The landscape is relatively densely forested. The average altitude is 502 m above sea level.
In the village you will find, for example, a multi-purpose playground, a library, a primary school and a kindergarten.
