Ford and completed in 1914. Ford worked in the Cape Province, Orange Free State and Transvaal and especially designed DRC buildings, of which the most outstanding is probably that of the Mother Church in Kroonstad
The Sarel Cilliers memorial is on the grounds of the NG Moederkerk in Kruis Street, Kroonstad.
Cilliers is depicted standing on a gun carriage, making the Blood River vow.
The building is protected as a Provincial Heritage Site
