Cubic and hexagonal domains with sizes of 1–10 $\mu$m in GaN were visualized using a newly developed cryogenic scanning photoluminescence (PL) microscope with a sub-$\mu$m spatial resolution. PL emissions at wavelengths of 358 and 380 nm were used to discriminate the polytype. The coverage of the hexagonal phase on the surface changes in accordance with the volume fraction of the polytype as determined by X-ray diffraction.
