A period room is a display that represents the interior design and decorative art of a particular historical social setting usually in a museum.
Though it may incorporate elements of an individual real room that once existed somewhere, it is usually by its nature a composite and fictional piece.
[1][2] Period rooms at encyclopedic museums may represent different countries and cultures, while those at historic house museums may represent different eras of the same structure.

[4] In the 21st century, the focus has shifted toward using period rooms in new ways[5] or in diversifying them.
