Abstract: Let Gamma be a congruence subgroup of the Picard modular group of animaginary number field k, and let D be the associated symmetric space. Wedescribe a method to compute the integral cohomology of the locally symmetricspace Gamma\D. The method is implemented for the case k=Qi and k=Qsqrt-3,and the cohomology is computed for various Gamma.
