The South African Slave Church Museum (also known as the South African Sendinggestig Museum) was established in 1977.
The theme of the museum is Christian missionaries and the impact the missionaries had on slaves and the indigenous people of South Africa. Exhibitions at the museum also carry themes about the history of the South African Gestig Congregation, the history of the museum building and Christian mission work and mission stations.
The Museum is housed in the oldest indigenous mission church in the country built by local Christians.
The museum building is architecturally unique as it was South Africa’s first building in the form of a basilica with an Apsis. All its windows are small scale replicas of this floor plan. It has the only surviving example of a steeply pitched lime-concrete roof – a form of construction developed at the Cape specifically for flat roofs. Its façade features Corinthian pilasters carrying a moulded Cornice and a Gable with a circular ventilator and four Urns.
