Fearful German Neighbors Prepare for Potential Wars and Unearth WWII Bunkers: 'Russia Threatens Us All'

berlin, germany - In light of Putin's continuous threats with nuclear weapons, Germany is shaken awake, with anxious citizens fearing the worst.

A secret door next to Humboldthain Park leads downwards. Underneath the former jeweler lies a massive refuge for the neighborhood. Opening a heavy steel door four steep flights down, visitors enter a space where a shelter was built during the economic crash of the late twenties after a threat of war.

During World War II in 1941, the Nazis expanded this underground refuge. However, it proved to be inadequate against heavy bombs and rockets, with space for only two thousand people in a city of nearly four million.

A tour through the eerie corridors reveals small toilet pots, bunk beds, and grey air ventilators. Signs with 'Ausgang' indicate exits in every part of the labyrinth. One room displays an American ad poster from 1981, warning people to 'Book a trip to Europe while you still can.'

Martina Baltkalne (40), a guide from Lithuania who leads tourists, points out the history of the Berlin Cold War hotspot. The city was divided between East and West, with the reminder that only in Zone 4 in Grunewald could one survive an atomic bomb.

The current tension has prompted the German government to advise citizens to restock emergency supplies and consider building bunkers in basements. An app helps locate the nearest shelters, as fearful neighbors prepare for a potential war scenario.
