ДОТ № 720 КаУР

{ "title": "DOT № 720 Karelian Fortified Region", "description": "DOT № 720 is a two-story concrete machine gun bunker (долговременная огневая точка, or DOT) located on the Karelian Isthmus in Russia's Leningrad Oblast. It forms part of the historical Karelian Fortified Region (Карельский укреплённый район, КаУР), a extensive Soviet defensive system constructed primarily in the 1930s and early 1940s along the border with Finland.

These structures were built with thick reinforced concrete walls and ceilings to withstand artillery fire. The two-story configuration typically housed a crew in the lower level, with the main machine gun emplacement (likely for a PM M1910 or similar heavy machine gun) and observation ports on the upper level. Such bunkers were designed for long-term defense and were often integrated into trench lines, obstacle networks, and larger fortified positions.\n\n Today, the bunker remains as a historic military relic within a landscape dotted with similar fortifications. While many structures in the Karelian Fortified Region have been dismantled or are in states of decay, some, like this DOT, persist as tangible evidence of
