The Fortification System of the Karola-line

Abstract

My research results are new in that this is the most detailed, up-to-date and most widely used description of the locations of the former protection system at the southern part of the Northern Central Mountains, on the Aszód–Gyöngyös section of the Karola Line. To the best of my knowledge, no one has even dealt with the research and location of the reinforce system itself, so the publications on the topic so far are extremely short and contain only general, comprehensive information about the Karola Line. Thus, my research aims to fill this gap of the Hungarian military history, and to provide a supplement/basis for the already completed and ongoing
or planned World War II metal detecting searches to pinpoint the locations of the defensive elements of the terrain.
For my research on the Karola Line, I examined the maps, reports, and sketches of the Soviet troops as well as World War II local history research on the settlements along on the supposed location of the Line, aerial photographs, and field reconnaissance results and, in some places, the experience of metal detecting.
