Given a Hermitian symmetric spaceMof noncompact type, we show, among other things, that the metric compactification ofMwith respect to its Carathéodory distance is homeomorphic to a closed ball in its tangent space. We first give a complete description of the horofunctions in the compactification ofMvia the realisation ofMas the open unit ballDof a Banach spaceequipped with a particular Jordan structure, called a-triple. We identify the horofunctions in the metric compactification ofand relate its geometry and global topology, via a homeomorphism, to the closed unit ball of the dual space. Finally, we show that the exponential mapatextends to a homeomorphism between the metric compactifications ofand, preserving the geometric structure, whereis the Carathéodory distance onD. Consequently, the metric compactification ofMadmits a concrete realisation as the closed dual unit ball of.
