Abstract. Let R ⊂ T be a minimal ring extension of (commutative inte-gral) domains. If R is integrally closed in T, then R is a going-down domain if and only if T is a going-down domain. The preceding assertion can be generalized to the context of weak Baer going-down rings. If R is integrally closed and T is a Prüfer domain, then R is a Prüfer domain. If T is integral over R and T is a going-down domain, then R is a going-down domain if and only if the extension R ⊂ T satisfies the going-down property. An example is given of an integral minimal overring extension R ⊂ T of two-dimensional domains such that T is a going-down (in fact, Prüfer) domain and R is a treed domain which is not a going-down domain. 1
