contents We study dipolar excitons confined at 330 mK in a square electrostatic lattice of a GaAs double quantum well. In the dipolar occupation blockade regime, at 3/2 filling, we evidence that excitons form a face-centred superlattice quantum solid. This phase is realised with high purity across 36 lattice sites, in a regime where the excitons mean interaction energy exceeds the depth of the lattice confinement. The superlattice solid then closely relates to Wigner crystals.
