The UNESCO Creative Cities Network (UCCN) was created in 2004 to promote cooperation with and among cities that have identified creativity as a strategic factor for sustainable urban development. The Network contains seven creative fields: literature; crafts and folk art; design; film; gastronomy; media arts and music. Reykjavík has been a UNESCO City of Literature since 2011.
The UCCN is a growing network with new cities being designated every other year. The title is a permanent one, as long as the designated cities stay active within the network.
