Dubai in the 60s and about 2008. I put these together from a slideshow I was sent as I didn't think I could get access to this building to take my own shot, although I do work in the left foreground building about once a year.
I have witnessed the incredible changes in Dubai during visits over the past 14 or so years. It really is quite jaw-droppingly unbelievable.
The tall building you can just see at the back left side with the red lights on top is the Burj Khalifa Tower (World's tallest building) under construction.
