Basements, also known as cellars, are underground rooms or spaces that are typically used for storage. They are often found in residential homes and commercial buildings, and can be used to store items such as food, wine, tools, and other items. Basements are also sometimes used as living spaces, such as bedrooms, bathrooms, and laundry rooms. Basements can also be used for recreational activities, such as home theaters, game rooms, and gyms.
