That looks like the Athlone Cooling Towers in Cape Town.

A guy I know used to be a taxi driver in the early 80's. He'd often pick up tourists from the airport and bring them to the city, which meant he'd have to drive past those towers. One day a few Texan tourists were remarking about how poor some of the non-white communities and townships on the side of the freeway looked, and said that the apartheid government should do more to help them. He pointed to the cooling towers:

"You see those big grey things there? Those are giant soup pots. You won't find them anywhere else in the world. Every month they cook millions of liters of soup that is distributed for free to the poorer communities."

They believed him.
