A cellar is an underground room or space typically used for storage. It is often found in homes, especially in regions with colder climates, where it can help preserve food and beverages. Cellars are commonly used to store items like wine, vegetables, and canned goods, taking advantage of the cool, dark environment. In addition to storage, cellars can also serve as living spaces or recreational areas. Some people convert their cellars into cozy lounges or game rooms. The design and purpose of a cellar can vary widely, influenced by factors such as local building practices and personal preferences.
