It is shown that the minimal Left-Right symmetric model admits cosmic string, domain wall and conditionally, monopole solutions. The strings arise when the SU(2)R is broken and can either be destabilized at the electroweak scale or remain stable through the subsequent breakdown to U(1)EM. The monopoles and domain wall configurations exist in the SU(2)L⊗ U(1)Y symmetric phase and disappear after subsequent symmetry breaking. Their destabilization provides new sources of non-equilibrium effects below the electroweak scale. Several defect-mediated mechanisms for low energy baryogenesis are shown to be realisable in this model.
