LANDSCAPE TRANSFORMATIONS IN THE HISTORICAL CAPITALS OF LITHUANIA DURING THE 13^TH-14^TH CENTURIES

The castles of Kernavė, Trakai and Vilnius define the core territory of the nascent Lithuanian state. The transformation of the landscape in order to create power centres within the territory of Lithuania at the end of the 13^th century into the 14^th century is a testimony to the ambitions of the ruling Gediminid dynasty. The article presents the results of research carried out in 2018–2019 based on LiDAR data analysis, geophysical surveys, and archaeological investigations with minimal destructive impact. To reconstruct the paleorelief of the landscape, pedological methods were applied. In Kernavė, the most extensive landscape transforming works relate to the construction of hillforts: the steep ridges of the Neris river valley were artificially separated from the upper terrace and thereby transformed into two hillforts, separated by a defensive moat. For the construction of a brick castle in Old Trakai, a site exploiting the advantages of the natural terrain was chosen. Here a suitable location was found that could with few efforts be transformed into a hillock encircled with a moat. The brick castle at New Trakai was built on a peninsula going into a lake and further separated by deep moats. In scholarly writings, it has been assumed that this hillfort was of artificial origin. But the research has challenged this by demonstrating that the hillfort of the Peninsula Castle in New Trakai was merely a transformed glacial hill.
