Old Fort – Kotze St – The ZAR decided to build a fort around the prison, which had been built in 1892 after the invasion of the Transvaal by Dr LS Jameson. The fort was to protect the city and the road to Pretoria. Guns could be mounted on the two bastions. It was built between 1896 and 1899 by Commandant (Lt.Col) Adolf Schiel, head of the Prison Services. Designed by Sytze Wierda with the Engineer GH van Winsen. The fort was completed by 12 June 1899. It never played a part in the ABW> Various famous political and other people were incarcerated here. It functioned as a prison until 1987. Declared a National Monument on 27 November 1964.
