We enter our mythical museum of curiosities again and this time travel beneath the Baltic Sea to find something very strange. Again, this object isn't a work of fiction, nor is it something ethereal. It is a real existing thing that can be studied... but what is it? Of all the structures of unusual nature that are talked about, this one has gone under the radar but I find it one of the most fascinating. It certainly appears as though there is a crashed UFO under the Baltic Sea.
