Sana'a is the capital of Yemen with origins lost in the mists of time and is considered one of the oldest continuously inhabited cities in the world.
Protected by the Unesco, it became an important citadelle on the road from Aden to Mecca.
Sana'a can also pride itself on having the first skyscrapers in the world, some of which are more than 1000 years old (the 6 or 7 storey houses are built into the side of the mountain, and look as if they soar up breathtaking heights)
The walls surrounding the old center date from the 9th and 10th centuries.
The famous market (the souk) was already in existence in the pre- Islamic period, and has changed little since that time.
30.000 people live in the Old City, some in houses which date back more than 400 years.
The grand mosque of Sana'a was built at the time of Prophet Mohamed, and is acknowledged today as one of the oldest in the Islamic world.
