I was just browsing near the city Bratislava, on the shores of danube. There are lot of strange and interesting forgotten places. At least for me. I will show you some.
This is an old bunked, build in 1938 as a defence against hitler's germany.
This place is was a first and biggest airfield in former Austrian-Hungarian empire, one of the first ever in Europe. Raised in 1907, near village called fisamend
Currently there almost nothing left, just couple of buildings an field.
