We explore prospects for optical lattice confinement of Strontium Rydberg atoms. In particular we identify a magic frequency in the blue-detuned spectrum which allows for simultaneous trapping of ground and Rydberg states and show that the overall lifetime of such systems is only limited by spontaneous decay. Further, it is found that the Strontium nS states feature attractive van der Waals interactions, which is used to devise a scheme for the robust generation of many-body Schroedinger cat states. The latter exemplifies the potential of the described approach for quantum information schemes and metrology by exploiting the extreme interactions between Rydberg atoms.
