Query: Domain Walls on Singularities   We describe domain walls that live on $A_2$ and $A_3$ singularities. The
walls are BPS if the singularity is resolved and non--BPS if it is deformed and
fibered. We show that these domain walls may interpolate between vacua that
support monopoles and/or vortices.
