  In this article we discuss how to construct canonical \emph{strong}
Carrollian geometries at time/space like infinity of projectively compact Ricci
flat Einstein manifolds $(M,g)$ and discuss the links between the underlying
projective structure of the metric $g$. The obtained Carrollian geometries are
determined by the data of the projective compactification. The key idea to
achieve this is to consider a new type of Cartan geometry based on a
non-effective homogeneous model for projective geometry. We prove that this
structure is a general feature of projectively compact Ricci flat Einstein
manifolds.
