The Guzz
You will find an abandoned military graveyard called the Guzz outside Plymouth, England. It houses once advanced watercraft that formed the nuclear submarine fleet back in the Cold War. HMNB Devonport is home to various submarines, many of whose nuclear engines remain intact. Britain stored these things near residential areas, which made the locals angry. It is very possible that this will impact their health!
Hara Submarine Base
Hara Submarine Base had been a busy Soviet Union military hub for four decades. It has since been abandoned and vandalized. Built by the Russian military in the ‘60s, it was the base of operations for the occupation of Estonia. Who would have thought that hundreds of military personnel used to live here? In 1989, Estonians linked hands with the neighboring countries and dismantled this base. The world paid attention and chased the Soviets out after the USSR collapsed.
