Riddle #2

This Riddle, once again posted by +South Africa Travel Online, (original post is here) was meant for everyone who have travelled in South Africa before. If you've been to the location you should recognise it instantly - which I did. Some others as well.

I'm reposting it here for:

1. Those of you who've been there and would enjoy recognising it from memory, and
2. ...to show that even if you haven't been there before, provided that you make one or two assumptions, it is still possible to solve the riddle. 

So the riddle, once again, provides a photograph (below) and simply reads: Where am I?

Do you know the answer or can you figure it out using online and other search tools?

Enjoy.
