We introduce novel types of self-trapped extended optical structures, which can be generated in both self-focusing and self-defocusing nonlinear media in the form of two-dimensional vortex lattices. We discuss a link of these novel objects with other types of spatially localised self-trapped states, such as vortex solitons and ring-shaped rotating clusters of solitons.
