Abstract: Let $ G/K$ be an irreducible Riemannian symmetric space of the non-compact type and denote by $ \Xi $ the associated crown domain. We show that for any proper action of a cyclic group $ \Gamma $ the quotient $ \Xi /\Gamma $ is Stein. An analogous statement holds true for discrete nilpotent subgroups of a maximal split-solvable subgroup of $ G$. We also show that $ \Xi $ is taut.
