Takwa ruins are the remains of a thriving 15th and 16th century Swahili trading town before it was abandoned in the seventeenth century. It is not only important because of its period of occupation but also because of its dense settlement and its relatively well-preserved remains. The unique Friday Mosque with a large pillar a top the qibla wall is among the most notable features.
This pillar is believed to symbolize the burial of a Sheikh below the wall. The position of the site at the narrowest location on the whole island, was most probably a strategy. Takwa’s position/location with shallow waters must have been of considerable importance especially during its peak, when many of the sails that came into view were likely to be hostile. Therefore, access to the site must have been primarily from the shallow channel which could only admit vessels of shallow draft.
