  Some years ago, Atiyah and Manton described a method to construct approximate
Skyrmion solutions from Yang-Mills instantons. Here we present a dynamical
realization of this construction using domain walls in a five-dimensional gauge
theory. The non-abelian gauge symmetry is broken in each vacuum but restored in
the core of the domain wall, allowing instantons to nestle inside the wall. We
show that the worldvolume dynamics of the wall is given by the Skyrme model,
including the four-derivative term, and the instantons appear as Skyrmions.
