Puzzling medieval castle in the middle of a frozen lake – but no one knows why A mysterious castle is located in the middle of a frozen lake in Poland, but nobody knows who owns it or how they finished it.
Construction of the Stobnica Castle started back in 2015, and was built on a man-made island in the middle of a lake, in the west of Poland.
The castle, which is built in a protected nature reserve, has been hugely controversial but flew under the radar until 2018, when local environmental groups and authorities became aware of the property.
Recent aerial footage revealed the castle, which took around nine years to build, and now sits completed on a snow-covered and frozen lake.
However, other rumours claim that the site was funded by money from offshore accounts or alternatively, the Polish company DJT could have been behind the building.
