  We discuss the structure of topological defects in the context of extra
dimensions where the symmetry breaking terms are localized. These defects
develop structure in the extra dimension which differs from the case where
symmetry breaking is not localized. This new structure can lead to corrections
to the mass scale of the defects which is not captured by the effective theory
obtained by integrating out the extra dimension. We also consider the Higgsless
model of symmetry breaking and show that no finite energy defects appear in
some situations where they might have been expected.
