Abstract: A space is rigid if its only self-homeomorphism is the identity. In response to a question of Jan van Mill, Ancel and Singh have given examples of rigid $ n$-dimensional compacta, for each $ n \geqslant 4$, whose squares are manifolds. We construct a rigid $ 3$-dimensional compactum whose square is the manifold $ {S^3} \times {S^3}$. In fact, we construct uncountably many topologically distinct compacta with these properties.
