Suspiria's array was a space station in the Delta Quadrant. Built by a Nacene individual known as Suspiria, it was similar to the Caretaker's array in configuration and surface composition, but only a tenth its size. According to scans taken by the USS Voyager, the facility was at least three hundred years old, as of 2372.
Suspiria's array contained a colony of over two thousand Ocampa, in which Suspiria encouraged the development of their metal abilities. They had also extended their lifespans. The facility didn't house Suspiria herself, as she instead resided in Exosia, a subspace layer accessible through a nearby point in space called The Meeting Place.
