Lamu Fort Lamu Island

This squat castle was built by the Sultan of Paté between 1810 and 1823. From 1910 right up to 1984 it was used as a prison. It now houses the island’s library, which holds one of the best collections of Swahili poetry and Lamu reference work in Kenya, while the upstairs walkway is a gallery space for temporary exhibitions (stunning photos of the Tana River delta, when we visited). Entry is free with a ticket for Lamu Museum.
