The building historically known as Buhara Özbekler Tekkesi (Bukharan Uzbeks\' Dervish Lodge) is now the home of the Istanbul Design Center (İstanbul Tasarım Merkezi). The residence was constructed in the 17th century as a gathering place for pilgrims and dervishes from Turkestan, who were known as members of Nakhshbendi order. On their way to Hajj, pilgrims stopped by Istanbul for their customary visit to the Eyup Sultan and an Ottoman Sultan, who was the Caliph of İslamic World.
