Located in the northern part of the country, on the shore of the Gulf of Finland of the Baltic Sea, it has a population of 437,619 in 2020. Administratively a part of Harju County, Tallinn is the main financial, industrial and cultural centre of Estonia; the second largest city, Tartu, is located in the southern part of Estonia, 187.2 kilometres (116.3 mi) southeast of Tallinn. Tallinn is located 80.32 kilometres (49.91 mi) south of Helsinki, Finland, 320.56 kilometres (199.19 mi) west of Saint Petersburg, Russia, 300.84 kilometres (186.93 mi) north of Riga, Latvia, and 380 kilometres (240 mi) east of Stockholm, Sweden. It has close historical ties with these four cities. From the 13th century until the first half of the 20th century Tallinn was known in most of the world by its historical German name Reval. Tallinn, first mentioned in 1219, received city rights in 1248, but the earliest human settlements date back 5,000 years.

The first recorded claim over the land was laid by Denmark in 1219, after a successful raid of Lyndanisse led by King Valdemar II, followed by a period of alternating Scandinavian and Teutonic rulers. Due to its strategic location, the city became a major trade hub, especially from the 14th to the 16th century, when it grew in importance as part of the Hanseatic League.

A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. A mountain differs from a plateau in having a limited summit area, and is larger than a hill, typically rising at least 300 metres (1000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges.Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, and through erosion by rivers and glaciers.

High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction, such as mining and logging, and recreation, such as mountain climbing and skiing. The highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft).
