We present new VLBI observations of a complete sample of Brigthest Cluster Galaxies (BCGs) in nearby Abell Clusters. These data show a possible difference between BCGs in cool core clusters (two-sided parsec scale jets) and in non cool core clusters (one-sided parsec scale jet). We suggest that this difference could be due to the jet interaction with the surrounding medium. More data are necessary to discuss whether parsec-scale properties of BCGs are influenced by their peculiar morphology and position at the center of rich galaxy clusters.
