Here is an Aerial shot of Riyadh around 1999 provided by the General Directorate for Military Survey. It was printed in 2001 and was distributed to the public. I got mine from the Al-Jenadriyah Festival.

I'm no good in giving directions. You can enlarge the map and decipher the street. It is written in English so don't worry.

Or you can visit Google Earth. It's already been marked. Just type Riyadh.
