Abstract: We present numerical evidence for the existence of several types of new black hole solutions with a nonspherical event horizon topology in d>5 spacetime dimensions. These asymptotically flat configurations are found for specific metric Ansatze by directly solving the Einstein equations with suitable boundary conditions. We give a discussion of the properties of the higher dimensional generalizations of the balanced black ring solutions. Apart from that, we discuss also several types of static black hole solutions. They can be viewed as higher dimensional counterparts of the d = 5 static black rings, dirings and black Saturns. Similar to that case, the static configurations are supported against collapse by conical singularities.
