Unusual star cluster IRS 13E (near Sagittarius A*, the center of the Milky Way), which a new theory suggests may be composed almost entirely of black holes, with just a handful of regular stars mixed in.  Furthermore, these few regular stars are quite large, so they’ll likely go supernova and become additional black holes at some point.  An older theory posited that a single intermediate-mass black hole was responsible for the cluster holding together.
