2/49/D1

A military structure located near Břeclav, Czechia, in the South Moravian Region close to the Austrian border. The specific designation '2/49/D1' suggests a possible military grid reference or internal classification, but without corroborating historical or archaeological records, its exact purpose, construction period, and authenticity cannot be confirmed from available sources. The region has a complex military history related to the Cold War border fortifications, but this particular site's association with any known defensive line or installation is unverified.
