The Juozapinė Geomorphological Reserve, located in the Vilnius district near the village of Medininkai, is a unique geological and natural site featuring a distinctive fragment of a moraine mass. Established in 1992 to preserve this valuable natural heritage, the reserve covers an area of 251 hectares in the Medininkai Highlands, part of the northwestern section of the Ashmyany Upland. The terrain here was formed during the penultimate global glaciation and was partially altered during the last Ice Age, making this area one of the oldest in Lithuania.
The reserve is home to two significant natural landmarks in Lithuania: Aukštojas and Juozapinė Hills, which have long competed for the title of the "highest point in Lithuania." Using modern GPS
technology, specialists from the Geodesy Institute of Vilnius Gediminas Technical University determined that the difference between these two peaks is approximately one meter, allowing Juozapinė to boast having two of the highest peaks in the country.
Aukštojas Hill, named after the Baltic god Aukštojas and associated with Baltic mythology and cultural events, is a cultural and tourist attraction. The hill hosts ecological, ethnographic, and cultural projects, artistic events, and celebrations such as Mindaugas Coronation Day and World Earth Day. At the top of the hill stands the Baltic Sun Circle, which not only enhances the observation site but also holds deep symbolic significance, connecting the ancient history and beliefs of Lithuania.
