Syria has always been a centre where East and West meet and the cradle of civilization. All monuments, citadels, and ruins that tell the history of Syria introduce us to Palmyra. Palmyra, also known as Tadmor , is one of the most brilliant sites in the East. Its location is near a hot-water spring. After the Romans opened Syria Palmyra became as the ‘ City of Palm Trees’. Many people have governed it. For example, Auzaina, Queen Zanobia, Khalid Bin Al-Walid and many other Arab governors. Palmyra played a minor defensive role during the Islamic periods, but its destiny was no better that that of its queen. It has destroyed and the Romans replaced it with a military camp. The Palmyra ruins today cover a six-kilometre area. These include the Arch of Triumph, the Straight Street, and the Cemeteries. The Theatre located on the southern side, other buildings such as temples are scattered on the either side of the main street, and its museum situated between the ruins and the new town.
