This paper extends our previous research of an artificial mound in Kanda (Macedonia) from an archaeoastronomical point of view. In two previous papers, SB Research Group explained its archaeoacoustic research and established the existence of several cavities, likely burial chambers, inside the mound. This mound is essentially a massive earthwork, which, on its top contains two concentric - approximately oval frames and a large geoglyph in the center which resembles the mirror image of the Constellation of Cassiopeia. Through analyzing the symbolism of the Macedonian royal dynasty and through dating by the method of the precession of equinoxes, we established that the geoglyph is precisely pointing to Alexander’s birthday in the calendar. The precise alignment of the rising Sun, Cassiopeia and geoglyph on Alexander’s birthday in 356 B.C. suggests that geoglyph contains something related to him, possibly his tomb or the tomb of a close relative.
