[December 2011] There is a museum in Matera in south Italy, which shows how people lived in Sassi, the cave house.
They used dips in the cave to separate kitchen, bedroom, and so on, but basically it is just one room.
There were a donkey and chickens and other animals here, and behind the main bed, there was a toilet.
Imagining the smell of this room, I felt faint.
In this museum, there is the Japanese audio guide among other European languages, and there was not the Chinese guide, which is very rare nowadays.
