Letbe a symmetric space of noncompact type and rank. We prove that horospheres inXare Lipschitz-connected if their centers are not contained in a proper join factor of the spherical building ofXat infinity. As a consequence, the distortion dimension of an irreducible-rank-1 latticein a linear, semisimple Lie groupGof-rankkis. That is, given, a Lipschitzm-sphereSin (a polyhedral complex quasi-isometric to), and a-ballBinX(orG) fillingS, there is a-ballinfillingSsuch that. In particular, such arithmetic lattices satisfy Euclidean isoperimetric inequalities up to dimension.
