Yambe Island borders the southeast coast of Tanga Bay opposite of the Ras Nyamakuu peninsula. The island is surrounded by coral reefs and totally covered by coastal rag and mangrove forests. Uninhabited today, German records of the 19th century mention a small resident village of a local Arab ruler with his slaves. Maybe from his time or earlier, the island has ruins hidden in the forest, a walled grave and pillar tomb with large panels, enclosed by stones decorated with a herringbone pattern and a frieze of small panels. The herringbone pattern is a rare and unique feature Yambe Island in such tombs, but also sometimes found in ‘mihrabs’ of mosques.
