VOLOS, Greece  -- The Olympic flame left Greece's second largest port Thessaloniki, passing the ancient site of Dion, the town standing at the foot of the Olympus on Friday.

The flame covered four cities after Vassilios Papageorgopovlos, mayor of Thessaloniki, kindled the setting-off torch in Aristotle Square, passing first the ancient site of Dion, the Ancient Theatre, in its 400km journey.

The residents in the town of Dion and Katerini, 15 km northeast of  Dion, flocked into the ancient relic to cheer the arrival of the flame.

A big ceremony was put on in the site. The town band performed music  "Strose to stroma sou" (make your bed) composed by Mikis Theodorakis.

Pigeons were released after mayor's speech.

Dimosthenis Tambakos, the 2004 Athens Olympics rings' champion, lighted  the cauldron amid applauses.

"It's such a special feeling to run the torch, especially in Ancient  Theatre," said Tambakos, who had been to China during the 1999 world gymnastics championships in Tianjin.

"I have yet to qualify for the Beijing Games, but I will try my best in  trials."

The song "to pelago ine vathi" written by Greek famous musician Manos  Hatzidakis was sung in the ceremony.

Dion is a municipality and village in the Prefecture of Pieria, Northern Greece, best known for its museum and archaeological site.

The ancient city of Dion was a place of some importance, due to its  location at the foot of Mount Olympus. Archaeological findings show that  this was where Zeus was honored.

Leaving the Zion, the flame arrived at Volos, a port city, in drizzle. The Volos ceremony was staged in front of the city council.

The city mayor Alexanderos, who was named after Alexander the Great,  welcomed the flame by running the first leg of the city relay.

Vicky Kosmidou, the European karate champion, followed up as the second  city torchbearer to progress the journey.

"The karate is not a program included in Olympics, so I can't take part  in the Beijing Games though I am longing for it," said Kosmidou.

Volos was a city co-hosting the 2004 Olympic soccer matches and is  slating facilities for the 2013 Mediterranean Games.

The flame is to stay overnight in Lamia before entering the capital  city Athens on Saturday. The sixth day journey is going to get across  Amfiario (ancient site), Marathonas, Rafina and the Acropolis.
