Cellars are underground rooms or structures used for storage, typically for storing food, wine, or other perishable items. They can provide a cool and humid environment that is ideal for long-term preservation. In addition to food and wine storage, cellars may also be used for other purposes such as shelter during severe weather, as a root cellar for storing vegetables, or as a space for hobbies or workshops. Cellars can be found in homes, restaurants, bars, and other types of buildings. Modern homes may have basements that are used as cellars, while traditional homes may have separate underground structures specifically designed for this purpose.
