Pydna

(now Kitron ). A town of Macedonia, in the district Pieria, was situated at a small distance west of the Thermaic Gulf, on which it had a harbor. It was originally a Greek colony, but was subdued by the Maced on i an kings, from whom, however, it frequently revolted. Toward the end of the Peloponnesian war it was taken after a long siege by Archelaus. It again revolted from the Maced on i ans, and was subdued by Philip, who enlarged and fortified the place. It was here that Olympias sustained a long siege against Cas sander, 317-16 B.C. It is especially memorable on account of the victory gained under its walls by Æmilius Paulus over Perseus, the last king of Macedonia, 168 B.C.
