The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant in the constellation Leo, with at least 70 major galaxies (and many of them are spirals). Brightest member of the cluster, the central elliptical galaxy NGC 3842 contains a giant black hole  with 9.7 billion solar masses (!!) .  Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, which is hundreds of millions light years long and is one of the largest known structures in the universe.
