Ancient Period Evidence of life can be found beginning in the 10th-7th centuries B.C. There is a settlement known as
Mal Konstantinopol (Small
Constantinople) dating from
Roman times, and the life in the
Middle Ages is marked by
Markovi Kuli. In the vicinity of the town there is also an archaeological site known as Isar and is located at the village of
Marvinci. Also, there are the ancient mosaics of Valandovo, the necropolis discovered near Dedeli dating from the Iron Age, the monastery and the church dedicated to
St. George, etc. On the hill Isar, at the village of Marvinci near the town of Valandovo, there is a community from the early antique period called
Amphacsitida (Αμφαξίτις) in
Ancient Greek meaning "from both sides of
Axios (river). The hill is 40 to 45 meters high and is located over the mouth of Anska River, flowing into the
Vardar river. The
Acropolis of the town was strengthened by defence bulwarks. Most of the architectural findings show the existence of profane living objects, while the last phase shows the possible existence of a ceramic workshop. The construction method in the earlier primitive stages, is very different from the latest stages. According to the archeological findings, the town was first ruined in the 3rd century BC, in time of the Celtic invasion in 279 BC. The excavated construction material shows the cultural and economic development of the town throughout centuries of its survival. In the 5th and 4th century BC, stock was imported from
Corinth and
Ionia, in
Asia Minor. Ceramic from the Iron Age was found in the tombs and Greek amphorae from the classical and late
Hellenic period. Apart from the imported ceramics from the big manufacturing centers, there are also local ceramic products with native tradition and often simulating
Greek forms. During the
Hellenic era, the connections with the neighbouring leading cultural centres: Pela,
Beroia,
Amphipolis and
Thessalonica were strengthened. Ceramic plastic, jewels and coins were made in the pattern of these developed centres. The antique town on the Isar secured its economic development through agriculture, cattle raising and mining. The numerous mines in the region, as well as the pottery craft continued as a tradition in the Roman period.
Modern Period In the late 19th and early 20th century, Valandovo was part of the
Salonica Vilayet of the
Ottoman Empire. In 1913, as a result of the
Balkan Wars, the town became a part of the
Kingdom of Serbia, which in 1918 joined the
Kingdom of the Serbs, Croats and Slovenes. From 1929 to 1941 Valandovo was part of the
Vardar Banovina of the
Kingdom of Yugoslavia. From 1941 to 1944, during the
Axis occupation of Yugoslavia, Valandovo, as most of
Vardar Macedonia, was annexed by the
Kingdom of Bulgaria. ==Geography and climate==
