Abstract
The technology of erecting war shelters has been evolving over the centuries alongside the development of technology and building-oriented requirements. Many papers have been published on this subject in recent times. The ruins of the Wolf ’s Lair war fortress prompted the authors to write this work with a slightly different emphasis than the previous papers. In addition to a brief history of the objects, the work presents the design guidelines used in their construction and describes the construction solutions applied. In addition, where appropriate, the advantages and disadvantages of these construction solutions from an engineering point of view are highlighted.
