A stube (stiva (Romansh), stüa (Ladin and Lombard) is the traditional living area of the German-speaking Alpine areas (Austria, Germany, Switzerland), and the Italian regions of Valtellina, South Tyrol, Trentino and Ladinia. It is a room heated by a large stone- or tile-covered stove and entirely lined with wood to keep the heat inside; the woods mostly used for the wall panels are chestnut, walnut, spruce, and Swiss pine. The logs are inserted into the stove through a small door that opens on an adjacent room, usually the kitchen or the corridor.
