Avižieniai Eldership (Lithuanian: Avižienių seniūnija) is an eldership in Lithuania, located in Vilnius District Municipality, northwest of Vilnius. It is the most populous eldership in the municipality.[2]
The eldership has a hillfort with a cultural layer dated to the beginning of 1st millennium A.D.[1] The landscape is dominated by rolling hills in the Riešė Upland. Many small wooded areas and swamps, but the landscape is undergoing rapid change due to suburbanization and its proximity to the city. Notable rivers include Riešė and Čekonė, and there are several small lakes, such as Gilužis, Ežeraitis, Notiškis and Varlinka.
Avižieniai were known since the Interwar for their gardens. In the 19th century, an orthodox church was built in Bukiškis. It was damaged during World War II, and only ruins and the basement remain, and are known to have the buried corpses of a general. The church rebuilding project was initiated in 1990, and the church was rebuilt in 2007.
Coat of arms for Avižieniai was created in April of 2023 and is awaiting approbation. It depicts oats as Avižieniai is from Lithuanian – aviža (oat).[3]
There are 27 villages located within the eldership, the largest of which areAvižieniai, Bukiškis, Riešė (of which only half of the village is located in the eldership, the other half belongs to Riešė Eldership), Bendoriai and Klevinė.
