The highest point in the Republic of Lithuania – Aukštojas Hill rises 293.84 metres above Baltic Sea level. You can visit it in Vilnius district, in the Juozapinė Geomorphological Reserve near the village of Medininkai. A boulder rolled onto the summit and a geodetic marker set in concrete record its name and height. About 10,000–15,000 years ago, the whole territory of our present-day state was covered by a glacier. Various moraine deposits accumulated at its edge: boulders, gravel, grit, sand and shingle. The powerful waters of the melting glaciers smoothed the surface of the Medininkai Upland, so it is now fairly flat, with no hills or mounds that stand out obviously. That is why, looking out from the observation tower on the summit of Aukštojas, almost 300 metres above sea level, it is hard to grasp that this is Lithuania's highest peak. It is worth noting that there are no lakes in the Medininkai Upland. Scientists say there once were, but the flowing glacial current drained the water and broke down the shores. Today the main elements of this landscape – valleys, gullies, small ravines and hills – are large, with gentle slopes or ridges. For a long time the highest point in Lithuania was thought to be Juozapinė Hill, which also stands in the Medininkai Upland, about 1 km from Aukštojas. In 2004, using modern satellite GPS technology, specialists from the Institute of Geodesy at Vilnius Gediminas Technical University calculated that the difference between the two peaks is about one metre. So Juozapinė Geomorphological Reserve can boast of having Lithuania's two highest peaks. Aukštojas Hill is a natural feature of special symbolic significance for Lithuania; it has been separated from the county's agricultural land and handed over for tourism and cultural purposes. Various projects are carried out here and art events are held on the hill. It is planned to mark Mindaugas's Coronation Day (6 July) and World Earth Day (20 March) here every year, and to host World Lithuanian Games competitions and ecological, ethnographic and other cultural events. Visitors to Aukštojas are invited to admire the small pine wood, the planted oak grove and the special artistic feature that adorns the hill – the Baltic Sun Wheel. For tourists' convenience there are benches, a car park, bicycle stands, an observation tower and signposts. Aukštojas is the name of the supreme Baltic god, mentioned in written sources since the 14th century – the highest deity of the sky, the creator of the world and the guardian of the principles of morality and justice. The supreme god is the first, eternal and without beginning. The ancient Lithuanians also called him by other names: Praamžius, Sutvaras, Vaisgamtis, Labdarys, Gyveleidis, Ūkopirmas and others. Dalia Matulaitė's sculptural composition, unveiled on the summit of Aukštojas in 2012, is not only an artistic feature adorning the hilltop but also an enriching symbol linking the hill with the history and faith of ancient Lithuania. The Baltic Sun Wheel symbolises an ancient altar. In its centre is something like a crown raised above Lithuania, surrounded by four granite horse heads. The Žemaitukas horses, looking towards the four corners of the earth, guard the crown and carry word of it to all parts of the world. In her work Dalia Matulaitė reflects Lithuanian folk art and features of the ancient Balts and other cultures. The sculptor hopes that this unique composition, created especially for this special place, will unite and bring together the Baltic tribes. The Baltic Sun Wheel is a place where all descendants of the Balts can light the fire of future unity. On 22 September, a fire is lit in the altar and, like a symbolic letter, sent to Baltic brothers and sisters in the neighbouring countries.
