  Nuclear Star Clusters are observed at the center of many galaxies. In
particular in the center of the Milky Way the Nuclear Star Cluster coexists
with a cen- tral supermassive black hole. The origin of these clusters is still
unknown; a possible formation mechanism is the decay of massive globular
clusters driven inward to the galactic center by dynamical friction and their
subsequent merging. By investigating this scenario by means of sophisticated
N-body simulations we found that this process could lead to a final product
which actually shows many of the observed features of the Milky Way Nuclear
Star Cluster.
