Locally symmetric spaces like SL(n,\mathbb Z)\backslash SLn(\mathbb R)/SO(n) contain immersed compact flat manifolds of dimension equal to the real rank. We give a lower bound for the contribution of these cycles to the homology of congruence covers. Similar results are proved for other families of locally symmetric spaces.
