Lamu Fort is a historic fortress located in Lamu, Kenya, originally built between 1813 and 1821 with assistance from Oman. It served as a base for Omani control of the East African coast but later lost its economic importance. Used as a prison during British colonial rule and after Kenya's independence, the fort now houses an environmental museum, library, and community event space. With its massive two-story stone structure, Lamu Fort offers a glimpse into the town's rich history and cultural heritage.
