Almost Einstein manifolds satisfy a generalisation of the Einstein
condition; they are Einstein on an open dense subspace and, in
general, have a conformal scale singularity set
that is a
conformal infinity for the Einstein metric. In case an almost Einstein
manifold is closed and
is a hypersurface we call the
corresponding Einstein metric conformally closed. Such Einstein
metrics represent a subclass of conformally compact
Poincaré-Einstein metrics. With respect to a special defining
function of the boundary every Poincaré-Einstein metric can be
expressed in normal form. Similarly, in this paper we discuss closed
manifolds, which admit multiple almost Einstein structures, whose
scale singularity sets intersect non-trivially. In a neighbourhood of
that intersection set
we describe the underlying
conformal geometry by normal form metrics and the
-doubling
construction of [24]. The set
is a totally umbilic
submanifold (of higher codimension).
