Diskussion:Bullaun
aus Wikipedia, der freien Enzyklopädie
I am studying bullauns on my island of Gotland and propose that those symmetrical and hemispherich with about 30 cm diameter were the hub of a vertical axis of early watermills. I would like to know were they exist outside Gotland, Ireland, Scotland and Wales.
