Ancient pyramidical structures, mausoleums, ruined cities and stone walls found in Somalia (such as the Wargaade Wall) are evidence of an old sophisticated civilization that once thrived in the Somali peninsula. The findings of archaeological excavations and research in Somalia show that this civilization enjoyed a lucrative trading relationship with Ancient Egypt and Mycenaean Greece since the second millennium BCE. This supports the hypothesis of Somalia and/or the adjacent Horn territories corresponding with the ancient Land of Punt. The Puntites traded myrrh, spices, gold, ebony, short-horned cattle, ivory and frankincense with the Ancient Egyptians, Phoenicians, Babylonians, Indians, Chinese and Romans through their commercial ports. An Ancient Egyptian expedition sent to Punt by the 18th dynasty Queen Hatshepsut is recorded on the temple reliefs at Deir el-Bahari, during the reign of the Puntite King Parahu and Queen Ati.
