Garanti Gallery (GG) was a cultural institution based in Istanbul, Turkey, specializing in design, architecture and urbanism. Through its various exhibitions, lectures, conferences, workshops and publications, GG filled a great gap regarding its areas of expertise in the city and the country in general. GG was founded in 2003 with the support of Garanti Bank.[1] Until August 2008, it organized thirty-one exhibitions at its 70m2 gallery on Istiklal Avenue.
