Walls 1,500 years old, still stand – almost (englishrussia.com)

Deep inside Siberia there is a lake, like thousands of others. And in the middle of this lake there is a small island. And on this island people have found the remains of an ancient fortress, which is more than fifteen hundred years old.

Excavation is needed to reveal it all. But even now it’s an interesting sight from a bird's-eye view in different times of the year.
