The Montagu Museum complex is comprised of three buildings, all within walking distance from each other in Long Street. Joubert House, built in 1853 on a sub-division of the original Uitvlucht farm, depicts the lifestyle of the latter part of the nineteenth century.

The Old Mission Church, built in 1907, houses the administrative offices, as well as the archive containing all documents, photographs and Africana relating to the history of Montagu.
