Lamu like the other East African coastal cities was already established by traders from Oman in the tenth and eleventh centuries. In the 14th century Lamu was an important trade center colonized by the arabs. Portuguese traders came and went. At the beginning of the 1800 Omanis settled in Zanzibar and reasserted Omani authority in the area under the Sultan. The Lamu Fort (here on the right) was built around 1810 and the governor (Liwali) had his residence built right behind it at about the same time (Subira House today!).
Lamu is the cradle of Swahili poetry. Intermarriage and the introduction of Islam produced the Swahili culture, after the Arabic word sahil, for coast. There is a treasure of oral poetry originating from the neighbouring islands - poetry is still remembered and much read and appears in everyday life. Older settlements have been traced on the Island of Manda, at Taqua Ruins -easy to visit by motorboat at high tide and in the villages of Pate Island, North of Lamu.
