To the town which he built in this locality Tiridates gave the name of Dara, a word which the Greeks and Romans elongated into Dareium.

Unfortunately, modern travellers have not yet succeeded in identifying the site, which should, however, lie towards the East, perhaps in the vicinity of Meshed.
We may presume that Tiridates, when he built this remarkable city, intended to make it the seat of government.

Hecatompylos, as a Greek town, had the same disadvantages, which were considered in later times to render Seleucia unfit for the residence of the Parthian Court and monarch.

Dara, like Ctesiphon, was to be wholly Parthian.

Its strong situation would render it easy of defence; its vicinity to forests abounding in game would give it special charms in the eyes of persons so much devoted, as the Parthian princes were, to the chase.
