  We investigate the presence of localized structures for relativistic scalar
fields coupled to impurities in arbitrary spatial dimensions. Such systems
present spatial inhomogeneity, realized through the inclusion of explicit
coordinate dependence in the Lagrangian. It is shown that, in stark contrast to
the impurity-free scenario, Derrick's argument does not present a strong
hindrance to the existence of stable solutions in this case. Bogomol'nyi
equations giving rise to global minima of the energy are found, and some of the
ensuing BPS configurations are presented.
