The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole.
The North Pole is the northernmost point on the Earth, lying diametrically opposite the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about 700 km (430 mi) away, though some perhaps semi-permanent gravel banks lie slightly closer. The nearest permanently inhabited place is Alert in the Qikiqtaaluk Region, Nunavut, Canada, which is located 817 km (508 mi) from the Pole.
While the South Pole lies on a continental land mass, the North Pole is located in the middle of the Arctic Ocean amid waters that are almost permanently covered with constantly shifting sea ice. The sea depth at the North Pole has been measured at 4,261 m (13,980 ft) by the Russian Mir submersible in 2007 and at 4,087 m (13,409 ft) by USS Nautilus in 1958.

Sarajevo ( SARR-ə-YAY-voh; Serbo-Croatian Cyrillic: Сарајево, Bosnian pronunciation: [sǎrajeʋo] (listen); see names in other languages) is the capital and largest city of Bosnia and Herzegovina, with a population of 343,000 in its administrative limits. The Sarajevo metropolitan area, including Sarajevo Canton, East Sarajevo and nearby municipalities, is home to 555,210 inhabitants. Nestled within the greater Sarajevo valley of Bosnia, it is surrounded by the Dinaric Alps and situated along the Miljacka River in the heart of the Balkans.
Sarajevo is the political, financial, social and cultural center of Bosnia and Herzegovina and a prominent center of culture in the Balkans, with region-wide influence in entertainment, media, fashion and the arts.Due to its long history of religious and cultural diversity, Sarajevo is sometimes called the "Jerusalem of Europe" or "Jerusalem of the Balkans". It is one of only a few major European cities to have a mosque, Catholic church, Orthodox church and synagogue within the same neighborhood. A regional center in education, the city is home to the Balkans' first institution of tertiary education in the form of an Islamic madrasa, today part of the University of Sarajevo.Although settlement in the area stretches back to prehistoric times, the modern city arose as an Ottoman stronghold in the 15th century. Sarajevo has attracted international attention several times throughout its history. In 1885, Sarajevo was the first city in Europe and the second city in the world to have a full-time electric tram network running through the city, following San Francisco. In 1914, it was the site of the assassination of Archduke Franz Ferdinand of Austria by local Young Bosnia activist Gavrilo Princip that sparked World War I, which also ended Austro-Hungarian rule in Bosnia and resulted in the creation of the Kingdom of Yugoslavia.
