What is what does foyer means?

A foyer is a space typically found just inside the entrance of a building, such as a lobby or entrance hall. It serves as a transitional area between the outside world and the interior of a building, and is often used as a place to greet guests, store coats and shoes, or display artwork. A foyer can range in size from a small alcove to a grandiose room, depending on the size and purpose of the building in which it is located.
