The Arusha Declaration Museum is located at Kaloleni area in Arusha city. It is the first ever museum in the Arusha region and also in the northern tourist circuit. The Museum is housed in the historical building which until 1967 was used as the social welfare hall for the people of Kaloleni area.

The building attained its unusual historical significance in 1967 when the National Executive Committee of the then ruling party Tanganyika African National Union (TANU) met and adopted the political and economic blue print popularly known as Arusha Declaration. This led, logically, to converting it in to a small political history museum on 1977

The Museum was opened to the public in 1977. It is exhibition portrays the development of Tanzanian societies from pre-colonial period to present with particular emphasis on the political and economic changes. The existing exhibition hall  has display depicting the fragmentary representation of pre colonial social development, the influence of foreign interaction before colonial rule, German and British rule, the struggle for independence, the union, formulation of the policy for self-reliance, and the development of Tanzania after the Arusha Declaration.
