Abstract: Let $I$ be an integrally closed ideal in a commutative Noetherian ring $A$. Then the local ring $A_{\mathfrak{p}}$ is regular (resp. Gorenstein) for every $\mathfrak{p} \in \mathrm{Ass}_{A} A/I$ if the projective dimension of $I$ is finite (resp. the Gorenstein dimension of $I$ is finite and $A$ satisfies Serre's condition (S$_{1}$)).
