Sanaa

Sana'a is believed by some to be the oldest continuously inhabited city in the World.  Visit the suq in Madinah Qadimah and you will believe it.  Things to see and do in the vicinity of Sana'a:

Dar al Hajjar - the 'palace on the rock' in Wadi Dhahr.  One of numerous former residences of the Imams.

Bait Baus - just south of the Haddah area lies the ancient village of Bait Baus.

Hammam Jaref - outside of the checkpoints but it is often possible to negotiate your way through them.
