The changes of defect structure of GaP:N epitaxial layers subjected to hydrostatic pressures up to 1.8 GPa are investigated by X-ray diffraction and photoluminescence. The observed changes are more pronounced at higher pressures and depend on the nitrogen concentration, c_{N}, and on initial defect structure. Especially complex hydrostatic pressure induced properties are observed for the sample with c_{N} > 10^{20} at. cm^{-3}. The model explaining the hydrostatic pressure induced defect structure changes is proposed.
