Some 75 kilometres to the north of Dar es Salaam lies Bagamoyo, once the embarkation port for slaves from the hinterland, and later the first German colonial capital. It is a place of considerable significance to world history, both as an entry point for Arab and European missionaries, explorers, and traders in East and Central Africa, and in the history of the infamous slave trade.Tourist attractions include the Kaole ruins dating back to the 12th century thought to mark one of the earliest contacts of Islam with Africa; the Old Fort built in 1860 for holding slaves for shipment to Zanzibar; the first Roman Catholic Church in East Africa built around 1868 used as a base to run a camp of about 650 freed slaves; the German colonial administration headquarters, the Boma, in the first capital of German East Africa; the Mission Museum displaying history of Bagamoyo; and the Livingstone Memorial Church among others.
