On the basis of high resolution ground-based images, taken with VLT and FORS1, 71 bona fide globular clusters were discovered in the halo of NGC 5128. Only 5 of these clusters were previously known. In a UV color-magnitude diagram for the complete sample of 71 clusters and a (U—V)0vs. (V—Ks)0 color-color diagram for a subsample of 23 clusters, the objects span a similar magnitude and color range as the globular clusters in the MW and M31. The GCLFs spanning −10.1 < MV < −4.9 and −9.3 < MU < −3.3 have been constructed. These are the deepest GCLFs of in a gE made so far. The Kolmogorov-Smirnov statistics show that GCLF of the giant elliptical NGC 5128 is consistent with the ones of spiral galaxies like the MW and M31.
