The most outstanding and valuable monument of the 18th century Azerbaijan is Sheki Khans' Palace. It was constructed in 1761-1762 as a summer residence of Hussein-khan Mushtad (grandson of Gadzhi Chelebi). The unique beauty two-storied building of the palace amazes with its magnificent interior and exterior. The facade of the palace is richly painted with anecdotal drawings displaying scenes of hunting and war as well as intricate geometrical and vegetative patterns. In the center is a huge stained-glass window from a multi-colored glass mosaic (It is remarkable up to 5 , 000 glass pieces were used per one square meter). Other smaller windows of the palace are also made of pieces of colored glass and covered with openwork stone lattices.
The basic material for the Palace construction was raw bricks, river stones, plane trees and oaks. The most amazing is that not a single nail or glue drop was used for the construction! Everything is in place due to a special solution the formula of which was lost forever.
There are only 6 rooms, 4 corridors and 2 mirrored balconies in the Palace. All the windows and doors of the palace were skillfully assembled from pieces of wood and colored Venetian glass. So the light getting inside the palace plays with all colors of a rainbow: red, yellow, blue, green…
Each room of the palace differs from one another and is skillfully decorated. All the walls and ceilings are painted with miniatures: mythical birds in paradise garden, unusual flowers and animals. The natural paints used for the pictures are admired by the visitors because of their bright colors. This kind of decoration gives the idea that in the second half of the 18th century Sheki khanate was the center of well-developed wall painting.
