We discuss the realization of metastable gravity on classical defects in infinite-volume extra dimensions .
In dilatonic Einstein gravity , it is found that the existence of metastable gravity on the defect core requires violation of the Dominant Energy Condition for codimension N _ { \mathrm { c } } = 2 defects .
This is illustrated with a detailed analysis of a six-dimensional hyperstring minimally coupled to dilaton gravity .
We present the general conditions under which a codimension N _ { \mathrm { c } } > 2 defect admits metastable modes , and find that they differ from lower codimensional models in that , under certain conditions , they do not require violation of energy conditions to support quasi-localized gravity .
