At the north of the precinct was a broad road, flanked with votive offerings and exedrae, and along the boundary were porticoes and chambers intended for the reception of the OEwpiac or sacred embassies; there are two entrances on this side, each of them through extensive propylaea.
After his death (337) a splendid monument, with porticoes and gymnasia surrounding it, known as the Timoleonteum, was raised at the public cost to his honour.
The site was excavated in 1894, and traces of a sacred agora with porticoes and other buildings, as well as the temple, have been found.
Most of these porticoes were of Roman period - the finest of them were erected, as we learn from inscriptions, by a lady named Epigone: one, which faced south, had a double colonnade, and was called the Bai-rn: close to it was a large exedra.
From this and other indications Professor Dorpfeld has inferred that the original plan of Mnesicles was to complete the south wing on a plan symmetrical with that of the north wing, but opening by a portico on to the bastion to the west; and to add on the inner side of the Propylaea two great halls, faced by porticoes almost in a line with the main portico, but with smaller columns.
