A century ago beehives were made out of tree logs cored inside.
They were put upright and equipped with conical roofs. To get to the plasters with honey beekeepers constructed little doors at the backs. The whole structures look a bit like houses for dwarfs.
I found these beehives in the open air museum of a priest-collector in Bujaków (village in south of Poland).
