From Project Athinai
Three buildings grouped together and standing on the western side of the Agora in a triangular space on the south of the Tholos might have been public offices. Several findings done during the excavations of this area suggest that they were used by the poletai (public auctioneers) responsible for the sale of confiscated properties and the leasing of the state-owned silver mines at Laureion.
The three buildings stood around a central courtyard, on its north, west and south sides. The was a well in the middle of the courtyard. The south building had three rooms in a row, the west building had eight rooms in two rows and the north building had two rooms with a common colonnade on the courtyard.
House of Simon the Cobbler
On the north, in the apex of the same triangular space, stood what was probably the house of Simon the Cobbler.
