A vestibule is a little area just inside the main door of a building, but before a second door. You often find vestibules in churches, because they help keep heat from escaping every time someone enters or exits.

The noun vestibule, pronounced "VES-tih-bule," probably comes from the Latin word vestibulum, which means “entrance court.” From about 1880 to 1930 vestibules were popular features in new homes because they create an additional barrier that keeps heat or cool air in and street noise out. If you have a vestibule, you can hang coats and leave shoes and gloves there instead of bringing them into the living room, kitchen and so on.
