  In this contribution, first results of deep VLT photometry (V,I) in the
central region of the Hydra I and Centaurus galaxy clusters are presented. In
both galaxy clusters, many star clusters have been identified down to the
turnover magnitude of the globular cluster luminosity function at V=26.0 mag.
They are distributed not only around the several early-type galaxies, but also
in the intra-cluster field, as far as 250 kpc from the cluster centers. Outside
the bulges of the central galaxies in Hydra I and Centaurus, the intra-cluster
globular cluster system is dominated by blue clusters whose spatial
distribution is similar to that of the (newly discovered) dwarf galaxies.
