In outline it is an irregular oblong, nearly an English mile in length and varying in width from half to two-thirds of a mile.

A broad and straight street, lined throughout with colonnades, runs from end to end of its length and passes at least five great buildings, which seem to be the temples and palaces of the Seleucid kings.

Two other streets cross this main street at right angles.

Whether the smaller thoroughfares took the same lines can be determined only by excavation.

It would be a gentle guess to think so.[36] [35] Tafrali, _Topographie de Thess._ pp.
