The problem of the interaction between the vortex lattice in superconductors with the void superlattice is investigated. It is shown that the effect of the void superlattice is strong enough and under conditions that can be easily realized, changes the symmetry of the latter. Then the minimum of free energy is reached for the vortex lattice whose unit cell before deformation in the vicinity of voids has the form of a parallelogram with, in general, unequal sides.
