by NEOnline/GK Greek archaeologists unearthed a tomb at Amphipolis in Macedonia Region of Northern Greece which is believed to belong to an important figure dating back to the last quarter of the Fourth Century BC. A large mound complex has been unearthed at the Kasta hill and lead archaeologist Katerina Peristeri said it certainly dated from after the death of Alexander the Great. "The land of Macedonia continues to move and surprise us, revealing from deep within its unique treasures," Greek Prime Minister Antonis Samaras said while visiting the mound complex on Tuesday. In 1977 the Vergina tomb was found in the region of northern Greece. The tomb belonged to Alexander's father, Philip II. The tomb is considered a unique world monument due to its size reaching a height of 3 meters and a total length of 497 meters. According to the archaeologists the monument bears the signature of famous ancient architect Dinocrates, a close friend of Alexander the Great. Archaeologists have found two sphinxes, thought to have guarded the tomb's entrance, and a 4.5-metre-wide road leading into it, with walls on both sides covered by frescoes. It is circled by a 497-metre marble outer wall. Ms Peristeri stressed that major historical events had taken place in the area of Amphiboles during the Macedonian Empire. Major generals and admirals of Alexander the Great are associated with the area, and it is there that in 311 BC Cassander exiled and then killed the wife of Alexander the Great, Roxanne, and his son, Alexander the Fourth.
