  This paper provides an overview of the theory of Bruhat-Tits buildings.
Besides, we explain how Bruhat-Tits buildings can be realized inside Berkovich
spaces. In this way, Berkovich analytic geometry canbe used to compactify
buildings. We discuss in detail the example of the special linear group.
Moreover, we give an intrinsic description of Bruhat-Tits buildings in the
framework of non-Archimedean analytic geometry.
