The most controversial of the forced removals occurred in the second half of the 1960s, with the expulsion of 65,000 coloureds from District Six, a vibrant inner-city ward of Cape Town, where whites, many of the slumlords, owned 56% of the property.  Against their will, District Six residents were moved out to the sandy townships of the Cape Flats.  In Johannesburg, the inner-city suburb of Sophiatown, where blacks could own freehold property, was another notorious site of forced removals.  Often long-established community institutions such as churches and schools had to be abandoned.

That is from the very good book by Hermann Giliomee The Afrikaners: A Concise History.
