The surrender of Nicaea by Phalaecus to Philip II, in 346 BCE, made the Macedonian king master of Thermopylae, and brought the Third Sacred War to an end.
[2] Philip kept possession of it for some time, but subsequently gave it to the Thessalians along with Magnesia.
But even if this is true, the town must have been rebuilt soon afterwards, since we find it in the hands of the Aetolians during the Roman wars in Greece.
William Martin Leake identifies Nicaea with the castle of Mendenitsa, where there are Hellenic remains.
