For me, the Clock Tower junction, which used to be a roundabout until 2-3 years ago (I hear), represents the centre of Al Ain.
Here’s a short video I created which shows the landmarks at each corner of this junction….
I say in the video that the Etisalat building is 200 yards/metres south of this junction: it’s more like half a mile!
Also, if you go west from this junction, I mention the Deer Roundabout, but you’ll also see Al Jahli Park on your left and after that the Thai Massage for ladies building on the left. On the other side of the roundabout is the Rotana Hotel.
There is a companion video here which does a 360-degree spin at the Sanaiya junction which you may wish to check out.
