  We present a class of quantum dimer models on the kagome lattice with full
translational invariance that feature a quantum many-body scar state of
analytically known entanglement properties within their spectra. Using exact
diagonalization on lattices of up to 60 sites, we show that non-scar states
conform to the eigenstate thermalization hypothesis. Specifically, we show that
energies are distributed according to the Gaussian ensemble expected of their
respective symmetry sector, illustrate the existence of the scar from bipartite
entanglement properties, and demonstrate revival phenomena in studies of
fidelity dynamics.
