This is the most visited lake in Pcinja district of Serbia, with its remarkable floating peat islands. Before the construction of the lake, there was a swampy terrain on that place, which was an imitation of an endless lush meadow in which Vlasina horses, cattle, sheep, and even the enemy army disappeared.
Thus, in the First World War, an entire Bulgarian cavalry regiment disappeared in the mud in the Vlasina mud (now a lake). Such a mystical disappearance of the army and cattle in Vlasina mud (tresava) was the reason for the creation of the legend of an unusual giant water monster. The myth of that unusual water (lake) monster, which “rang” after the construction of the earth dam in 1954, says that the lake was ruled by a monster that looked like a giant horse. It was rumored that the phenomenal water monster lived there for centuries, so it was added that it wandered from another planet, or God sent it to punish those who hid from him. However, it was mostly believed that it was some giant proto-animal. It was proved that this ghost has the magical power to quickly pick up the cattle that graze around the lake, eat it, so it satisfies hunger and rests at the bottom of the lake for a few days. The story of this lake monster remained just a story.
