ANA has a brief item on the restoration work ongoing at Philip II’s palace at Aigai. From the conclusion:
The restoration of the two-storey gallery (stoa) in the building’s front section was a “revelation” for archaeologists’ studying ancient architecture, as it contradicted earlier beliefs according to which such galleries were a later practice, dating in the 2nd century BC. The galleries’ architectural sections are built based on the “golden mean” ratio (1 to 1.6). Archaeologists believe that Pytheos was the palace’s architect, who had also designed the mausoleum of Halicarnassus, while the mausoleum’s sculptor Leocharis had also worked on the palace of Aigai.
