This Room Was Bricked Up for 40 Years Until Builders Accidentally Discovered It

After the First and Second World Wars, the need for bunkers and air raid shelters declined. However, these structures built to last through wars and explosions still exist to this day. They were hidden, but several people were lucky enough to stumble upon them.

In the south of England, which was heavily bombed by the Germans during the Blitz, anyone who had access to a garden was instructed to build a bomb shelter. The commonest type was the “Andersen” which used curved sheets if corrugated iron to form a roof over a shallow put dug in the ground. The whole shelter was covered in soil and often had a “blast wall” shielding the entrance. Such a shelter saved my parents, when their house was bombed to rubble a few weeks after the shelter was completed.

I still wonder if the people living in my old neighborhood even know about the bomb shelters in their backyards? A huge hole would be dug for like a swimming pool and a concrete box lowered with a door, that was 1950s. The old neighborhood still there. It would be interesting to know because I don't think those shelters could be easily removed.

With the world going today if I found a bunker in my property I would fix it for protection
