Fort Merensky
Middelburg, South Africa
Fort Merensky, also called Fort Wilhelm, stands on a prominent hill in a commanding position near Botshabelo, a former Berlin Mission Station (BMS), 13 kilometers from Middelburg on the road to Groblersdal. It was built in order to protect the mission's convert from attacks by the local Bantu tribes using dry wall construction.
