On the picture: One of the windows and its muqarnas ornaments. An example of the early-Ottoman style, which combines grandeur with rigor.

Muqarnas is a stalactite-like decoration initiated in Anatolia by the Seljuk (in the 11th – 12th century). They imported it from Iran. Later on it continued to be used in the late-Seljuk architecture of the Beyliks (14th century) and by the Ottomans up to the 19th century.
