Madinat al-Hareer (Arabic: مدينة الحرير, meaning "City of Silk"), is a proposed 250 square kilometer planned urban area in Subiya, Kuwait, an area just opposite Kuwait City which, upon construction, would include the Burj Mubarak al-Kabir , the world's tallest structure, a natural desert reservation of 2 square kilometres, a duty free area which will be beside a new airport, in addition to a large business center, conference areas, environmental areas, athletic areas, and areas that concentrate on media, health, education, and industry. The City of Silk will also include numerous tourist attractions, hotels, spas, and public gardens. As of this time, it is unclear as to the scope of this project, if it has received any approvals, or if it has the required funding; however, the city will be built in individual phases with total completion within twenty-five years. The development will cost an estimated 25 billion Kuwaiti Dinars (86.1 billion USD). Burj Mubarak al-Kabir should not be confused with the Al Jaber Tower proposed by the famous Italian architect Amero Marchetti, part of the planned "ethic city". If built the Al Jaber Tower would reach 1852 meters.
