The unusual Tomb of Eurydike lies slightly east of the Rhomaios Tomb. This double-chambered, barrel-vaulted structure, whose facade has yet to be revealed, is plastered with off-white mortar.
One of the short sides of the burial chamber is presented in trompe-l'oeil as a facade with a door and two windows framed by four Ionic half-columns, which support an Ionic three-tiered entablature and a frieze decorated with white palmettes.
A unique find is the marble throne with its richly carved and painted ornamentation; in particular, the back of the throne, which depicts Pluto and Persephone riding on a quadriga, is truly outstanding.
The wealth of this tomb, which had been plundered in antiquity, indicates a royal burial; on the basis of chronological data, it is attributed to Philip's mother Eurydike, inscribed dedications of whom have been found in the temple of Eukleia at Aigai.
