Establishing analytically constructed quantum scars within interacting systems has remained elusive until now. This work demonstrates such towers exist in two dimensional gauge theories via exact diagonalization, revealing anomalously low entanglement and long-range correlations, a conceptually different approach from prior numerical diagnostics. Introducing even minimal fermion mass immediately destroys this structure, highlighting its delicate balance against perturbation.
