The Mutual Building, in Cape Town, South Africa, was built as the headquarters of the South African Mutual Life Assurance Society, now the "Old Mutual" insurance and financial services company. It was opened in 1940, but before the end of the 1950s—less than 20 years later—business operations were already moving to another new office at Mutual Park in Pinelands ; since then Old Mutual has become an international business and their present head office is in Johannesburg.
