In the historic town of Hannassa in southern Somalia, ruins of houses with archways and courtyards have been found along with pillar tombs, including a rare octagonal one.[1]Port Dunford, situated nearby, also contains a number of ancient ruins, including several pillar tombs. Prior to its collapse, one of these structures' pillars stood 11 metres (36 ft) high from the ground, making it the tallest of its kind in the region.[2]
