  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 $SU(2)_L\otimes U(1)_Y$ 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.
