A global city (also called world city or sometimes alpha city or world center) is a city generally considered to be an important node in the global economic system. The concept comes from geography and urban studies and rests on the idea that globalization can be understood as largely created, facilitated, and enacted in strategic geographic locales according to a hierarchy of importance to the operation of the global system of finance and trade.
The most complex of these entities is the "global city", whereby the linkages binding a city have a direct and tangible effect on global affairs through socio-economic means. The use of "global city", as opposed to "megacity", was popularized by sociologistSaskia Sassen in her 1991 work, The Global City: New York, London, Tokyo though the term "world city" to describe cities that control a disproportionate amount of global business dates to at least the May 1886 description of Liverpool by The Illustrated London News. Patrick Geddes also used the term "world city" later in 1915. Cities can fall from such categorization, as in the case of cities that have become less cosmopolitan and less internationally renowned in the current era, e.g., Alexandria, Egypt; Coimbra, Portugal; Stralsund, Germany and Thessaloniki, Greece.
Victoria Peak (Chinese: 太平山, or previously Chinese: 扯旗山) is a mountain in Hong Kong. It is also known as Mount Austin, and locally as The Peak. The mountain is located in the western half of Hong Kong Island. With an altitude of 552 m (1,811 ft), it is the highest mountain on the island proper, but Tai Mo Shan is the highest point in the entirety of Hong Kong.
The actual summit of Victoria Peak is occupied by a radio telecommunications facility and is closed to the public. However, the surrounding area of public parks and high-value residential land is the area that is normally meant by the name The Peak. It is a major tourist attraction which offers views over Central, Victoria Harbour, Lamma Island and the surrounding islands.
