Abstract: Let be the Picard modular group of an imaginary quadratic number field k and let D be the associated symmetric space. Let be a congruence subgroup. We describe a method to compute the integral cohomology of the locally symmetric space G\D. The method is implemented for the cases k=Q(i) and , and the cohomology is computed for various G.
