Taipei City (/ˌtaɪˈpeɪ/; Chinese: 臺北市 or 台北市; pinyin: Táiběi Shì; Pe̍h-ōe-jī: Tâi-pak Chhī) is the capital of the Republic of China (Taiwan). Situated at the northern tip of Taiwan, Taipei is located on the Tamsui River; it is about 25 km (16 mi) southwest of Keelung, a port city on the Pacific Ocean. It lies in the two relatively narrow valleys of the Keelung (基隆河) and Xindian (新店溪) rivers, which join to form the Tamsui River along the city's western border. The city proper (Taipei City) is home to an estimated 2,618,772 people. Taipei, New Taipei, and Keelung together form the Taipei metropolitan area with a population of 6,900,273. However, they are administered under different local governing bodies. "Taipei" sometimes refers to the whole metropolitan area, while "Taipei City" refers to the city proper. Taipei City proper is surrounded on all sides by New Taipei.
Taipei 101 (Chinese: 台北101 / 臺北101), formerly known as the Taipei World Financial Center, is a landmark skyscraper located in Xinyi District, Taipei, Taiwan. The building ranked officially as the world's tallest from 2004 until the opening of the Burj Khalifa in Dubai in 2010. In July 2011, the building was awarded LEED Platinum certification, the highest award in the Leadership in Energy and Environmental Design (LEED) rating system and became the tallest and largest green building in the world. Taipei 101 was designed by C.Y. Lee & partners and constructed primarily by KTRT Joint Venture. In 2001, TFCC handed over the entire construction authority to Samsung C&T Corporation to expedite the process and to save KTRT Joint Venture's loss. The construction was finished in 2004. The tower has served as an icon of modern Taiwan ever since its opening.Fireworks launched from Taipei 101 feature prominently in international New Year's Eve broadcasts and the structure appears frequently in travel literature and international media.
