A
room is any distinguishable space within a structure. Usually, a room is separated from other spaces or
passageways by interior walls; moreover, it is separated from outdoor areas by an exterior
wall, sometimes with a
door. Historically the use of rooms dates at least to early
Minoan cultures about 2200 BC, where excavations on
Santorini,
Greece at
Akrotiri reveal clearly defined rooms within certain structures.
