Königsmühle, Königův mlýn or Králův mlýn is a vanished settlement near Háj u Loučné (Proud Grove) in the Ore Mountains. There were six houses in the settlement, today only ruins remain, surrounded by the beautiful nature of the mountain valley. 50 people lived in the settlement, who had to leave this place after 1945.
The former settlement Králův mlýn (King's Mill) is located near the road No. 223 in the valley of the river Černá voda below Hájský kopec (989 m). In the settlement, which once belonged to the larger village of Háj, 57 people lived in seven houses. The road from Háj to Králův mlýn is still decorated with knotty rowan and blueberries.
Wondering what happened to the residents of this picturesque mountain settlement? It was Sudeten Germans who were expelled after the war and the place was erased from the maps. Five houses in the settlement were dwelling houses and the other two buildings were probably mills. The villagers could grind grain in the king's mill, which was transported on the trade route from Bohemia to Saxony. A small pond with a dam also belonged to a mill. The last owner of this mill was the ancestor of the Klínovec pub owner.
The entrance to the basement of this former mill, which has survived to this day, was used by the residents of these five houses as an air raid shelter during the air raids during World War II.
