ABSTRACT
Interest into how the architects and builders of the medieval times have managed to design and realise the complicated structures without the modern knowledge has always been in the focus of art history studies. It is assumed, that the applied geometry has substituted the modern calculations. Several authors have advocated different approaches. This paper explores, how these methods and the approaches might have been applied to the building type, where geometric relations have been tested to a lesser extent—the Livonian castles, built during the medieval period on the territory of Latvia. This paper addresses the possible methods used to convey the original layout of these medieval structures from the general plan to the architectural details. Recent discoveries as well as analysis of different aspects of the castle geometry have been explored. The research is an ongoing project, as a part of the PhD studies on castle ruin conservation and display.
