When my family and me moved to our new house (it was 2013 or 2014 I don’t remember), my brothers and me had a really fun time exploring the “dungeons” of our new home. The building was built on an old seventeenth century villa, but that wasn’t clear from the outside since it was massively expanded and enlarged to build a apartment complex, and the whole complex was in urban area (even if at the time the villa probably was in the countryside). The old garden was behind our house, and it was destined to become a small public park, so access wasn’t permitted, even if it was quite easy to get there from our private garden. The thing that immediately caught our attention was that in the “public” garden there was a strange small hill, perfectly hemispherical, all covered by plants and grass. It totally looked man made, but we couldn’t understand its purpose.

Under the whole apparent there was a large complex of garages, and we bought two separate garages. In both of them there were entrance to small tunnels that seemed lead further into the ground. Exploring them was quite a test of courage, since they were really small and we feared that rats or insects could live there. I still remember the home made “cave exploring” suits my brothers and made for exploring those tunnels. We discovered that actually the further we went into those tunnels the less “life” (mostly mould, insects and spiderwebs) there was, even if air became more and more thick and rotten, almost unbreathable. We discovered that our garages’ tunnels were connected, and there were a couple other exits (presumably to other garages) that were walled up. But the most amazing thing we discovered was that one of the paths led to a small, empty room. The first one to discoverer it was my brother and he didn’t realise what it was at first.
