New location of the bema of the Pnyx

 
The area of the Pnyx is reshaped by the construction of a monumental semi-circular retaining wall and from then on the convening citizens have their backs turned against the city. Upon the Hill, begins the erection of two stoas that would delimit the area to the south of the Assembly Place. It seems as though their construction remained incomplete, whereas a while later the assembly of the Athenians was transferred to the theatre of Dionysos.
