The Qamaria (stained glasses windows) : - Possibly the most distinctive decorative feature of Yemeni architecture is the qamariya, the multicolored stained-glass windows that grace Yemeni buildings. The geometric patterns formed with colored glass sit above the windows and cast their patterns on the room. It is the symbol of Yemeni architectural culture, and adds a great beauty to Sanaa'a distinctive gingerbread skyline. All those who have walked through the Old Citys streets at dusk can testify to the fairy-tale beauty given by hundreds of illuminated qamariya to the city itself. Inside, the whitewashed walls are sprinkled with dots of colored light that creep down the walls as the sun falls in the sky.
