Grand shapes of the complex are visible from far away. In height, they are in considerable contrast with stocky “neighbours” – Mausoleums of Samanids and Chashma-Ayub. Kosh is a complex consisting from two classic madrassas that were built on one axis of western Bukhara in 16th century by the order of Abdullakhan. During his rule, Bukhara became cultural centre of Maveranakhr, separated lands were united due to which centralization of substantial wealth became possible. This explains the size and flatulency of the complex. The madrassas are located “face to face” to each other. First of them is “Modarikhon” which is translated as “Mother of Khan” from Farsi. It is smaller than Abdullakhan Madrassa and was built earlier, in about year 1566. We know this because of majolica inscription over the entrance. The name explains its history – It was built by Abdullakhan II for his mother. The layout is typical for the style of that period – there are two ayvans, inner yard is surrounded by the cells called khudjras, study room – darskhana on the left and a mosque on the right. Common hall is like a gallery with two corridors. The main façade is richly decorated with geometric ornament from mosaic bricks of different colours, painted majolica tympans, forming flower buds and the interior looks muted but fine. Second building named after Abdullakhan himself was built 23 years later. Its main entrance is decorated with volume portal rising over all nearby buildings, with two wings from two-level lodges that is a characteristic feature of Bukhara architecture. Central dome is laid on 16 arcs construction, decorated with stars. Inner yard is surrounded by Khudjras for students and teachers. In sunlight, majolica tiles of the façade of blue, turquoise and white colours gleams especially expressive and beautiful. Attention also should be paid to the doors. They are made from different types of wood without a nail and are decorated with the exquisitely detailed carvings. This complex is a pearl of Bukhara architecture. It used to be one of the most competent educational institutions of those times. By it scale, it is on the third place after Kukeldash and Miri Arab, and it retained its original view almost completely. It is interesting for those who favour true antiquity.
