Technical and technological construction questions of Memel / Klaipėda tunnel bombshelters of the World War II are analyzed in the following article. These questions help to reconstruct historical aspects of function and presumable purpose of these bombshelters during the siege of the town. The researches allowed to systematize the attributes, typical of such constructions. For the research of bombshelters’ constructions and materials, a comparative method was used: the received results were compared with analogous research results of Memel / Klaipėda and its surroundings’ structures – antiaircraft (Flak) and coast artillery battery – which functioned during the World War II. The constructions of remained German bombshelters are more than modest; the technological mistakes allow suppose, that the builders of the shelters didn’t dispose such material and human resources like ones of the batteries. Beside this, the durability of the bombshelters leads to believe that builders used some building materials of high quality, for example, the slag cement, the waterproof concrete and plaster.
