Tallinn
Tallinn is the capital and most populous city of Estonia. Situated on a bay in north Estonia, on the shore of the Gulf of Finland of the Baltic Sea, it has a population of 456,518 as of 2025 and administratively lies in Harju County. Tallinn is the main governmental, financial, industrial, and cultural centre of Estonia. It is located northwest of the country's second largest city, Tartu, however, only south of Helsinki, Finland. It is also west of Saint Petersburg, Russia, north of Riga, Latvia, and east of Stockholm, Sweden. From the 13th century until the first half of the 20th century, Tallinn was known in most of the world by variants of its other historical name Reval.
Tallinn received Lübeck city rights in 1248; however, the earliest evidence of human settlement in the area dates back nearly 5,000 years. The medieval indigenous population of what is now Tallinn and north Estonia was one of the last "pagan" civilisations in Europe to adopt Christianity following the Papal-sanctioned Northern Crusades in the 13th century. The first recorded claim over the place was laid by Denmark after a successful raid in 1219 led by king Valdemar II, followed by a period of alternating Scandinavian and Teutonic rulers. Due to the strategic location by the sea, its port became a significant trade hub, especially in the 14–16th centuries, when Tallinn grew in importance as the northernmost member city of the Hanseatic League. Tallinn Old Town is one of the best-preserved medieval cities in Europe and is listed as a UNESCO World Heritage Site.
In 2012, Tallinn had the highest number of startup companies among all capitals and larger cities in Europe. Tallinn is the birthplace of many international high-technology companies, including Skype and Wise. The city is home to the headquarters of the European Union's IT agency, and to the NATO Cyber Defence Centre of Excellence.
In 2007, Tallinn was listed among the top-10 digital cities in the world, and in 2022, Tallinn was listed among the top-10 "medium-sized European cities of the future".
Names and etymology
The name Tallinn is Estonian. It has been widely considered a historical derivation of Taani-linna, meaning "Danish-castle", conceivably because the Danish invaders built the castle in place of the Estonian stronghold after the 1219 battle of Lyndanisse.The Icelandic Njál's saga—composed after 1270, but describing events between 960 and 1020—mentions an event that occurred somewhere in the area of Tallinn and calls the place Rafala. Soon after the Danish conquest in 1219, the town became known in the Scandinavian and German languages as Reval. The etymology of Revala and derivatives in Estonian is unclear and hypotheses are numerous.
In international use, the English and German-language Reval as well as the Russian analog Revel were all gradually replaced by the Estonian name after the country became independent in 1918. At first, both Estonian forms, Tallinna and Tallinn, were used.

Henry of Livonia, in his chronicle, called the town with the name that is also known to have been used up to the 13th century by Scandinavians: Lindanisa.
In 1154, a town called قلون was recorded in the description of the world on the world map commissioned by the Norman King Roger II of Sicily and compiled by Arab cartographer Muhammad al-Idrisi, who described it as "a small town like a large castle" among the towns of 'Astlanda'. It has been suggested that one possible transcription, 'Qlwn', may have denoted a predecessor of the modern city and may somehow be related to a toponym Kolyvan, which has been discovered from later East Slavic chronicles. However, a number of historians have considered connecting any of al-Idrisi's placenames with modern Tallinn erroneous, unfounded, or speculative.
History
The first archaeological traces of a small hunter-fisherman community's presence in what is now Tallinn's city centre are years old. The comb ceramic pottery found on the site dates to about 3000 BCE and corded ware pottery to around 2500 BCE.Around 1050 AD, a fortress was built in what is now central Tallinn, on the hill of Toompea.
As an important port on a major trade route between Novgorod and western Europe, it became a target for the expansion of the Teutonic Order and the Kingdom of Denmark during the period of Northern Crusades in the beginning of the 13th century when Roman Catholic Christianity was forcibly imposed on the local population. The King Valdemar II of Denmark conquered Tallinn and northern Estonia in 1219.
Tallinn, then known more widely as Reval, was granted Lübeck town rights by the king of Denmark in 1248. In 1285, Reval became the northernmost member of the Hanseatic League – a mercantile and military alliance of German-dominated cities in Northern Europe. The king of Denmark sold Reval along with other land possessions in north Estonia to the Teutonic Order in 1346. Reval was arguably the most significant medieval port in the Gulf of Finland. Reval enjoyed a strategic position at the crossroads of trade between the rest of western Europe and Novgorod and Muscovy in the east. The city, with a population of about 8,000, was very well fortified with city walls and 66 defence towers. The city wall has been described as an outstanding example of German Medieval fortification architecture.
A weather vane, the figure of an old warrior called Old Thomas, was put on top of the spire of the Tallinn Town Hall in 1530. Old Thomas later became a popular symbol of the city.
In the early years of the Protestant Reformation, the city converted to Lutheranism. In 1561, Reval became a dominion of Sweden.
During the 1700–1721 Great Northern War, plague-stricken Tallinn along with Swedish Estonia and Livonia capitulated to Tsardom of Russia in 1710, but the local self-government institutions retained their cultural and economical autonomy within the Governorate of Estonia of the Russian Empire. The Magistracy of Reval was abolished in 1889. The 19th century brought industrialisation of the city and the port kept its importance.
On 24 February 1918, the Estonian Declaration of Independence was proclaimed in Tallinn. It was followed by German occupation until the end of World War I in November 1918, after which Tallinn became the capital of independent Estonia. During World War II, Estonia was first occupied by the Soviet army and annexed to the USSR in the summer of 1940, then occupied by Nazi Germany from 1941 to 1944. During the German occupation Tallinn suffered from many instances of aerial bombing by the Soviet air force. During the most devastating Soviet bombing raid on 9–10 March 1944, more than a thousand incendiary bombs were dropped on the city, which caused large-scale fires, as a result of which 757 people were killed and 20,000 left without shelter. After the German retreat in September 1944, the city was re-occupied by the Soviet Union.
During the 1980 Summer Olympics, the sailing events were held at Pirita, north-east of central Tallinn. Many buildings, such as the Tallinn TV Tower, "Olümpia" hotel, the new Main Post Office building, and the Regatta Centre, were built for the Olympics.
In 1991, the independent democratic Estonian nation was restored and a period of quick development as a modern European capital ensued. Tallinn became the capital of a de facto independent country once again on 20 August 1991. The Old Town became a World Heritage Site in 1997, and the city hosted the 2002 Eurovision Song Contest. Tallinn was the 2011 European Capital of Culture, and is the recipient of the 2023 European Green Capital Award. The city has pledged to cut greenhouse gas emissions by 40% by 2030 and takes pride in its biodiversity and high air quality. But critics say that the award was received on false promises since it won the title with its "15-minute city" concept, according to which key facilities and services should be accessible within a 15-minute walk or bike ride but the concept was left out of the green capital program and other parts of the 12 million euro program amount to a collection of temporary and one-off projects without any structural and lasting changes.
Geography
Tallinn is situated on the southern coast of the Gulf of Finland, in north-western Estonia.The largest lake in Tallinn is Lake Ülemiste, which serves as the main source of the city's drinking water. Lake Harku is the second-largest lake within the borders of Tallinn and its area is. The only significant river in Tallinn nowadays is the Pirita river, in the eponymous Pirita city district. Historically, a smaller river, called Härjapea, flowed from Lake Ülemiste through the town into the sea, but the river was diverted into underground sewerage system in the 1930s and has since completely disappeared from the cityscape. References to it still remain in the street names Jõe and Kivisilla.
The length of the seaside coast is, comprising three larger peninsulas. The city has a number of public beaches, including those at Pirita, Stroomi, Kakumäe, Harku, and Pikakari.
The highest point in Tallinn, at above sea level, is situated in Hiiu, Nõmme District, in the southwestern portion of the city. A large limestone cliff runs through the city. It can be seen at Toompea, Lasnamäe, and Astangu. However, the hill at Toompea, despite its prominence, is not geologically connected to the larger limestone cliff formation.
The rocks and sediments underneath Tallinn are of different composition and age. Youngest are the Quaternary deposits. The materials of these deposits are till, varved clay, sand, gravel, and pebbles that are of glacial, marine and lacustrine origin. Some of the Quaternary deposits are valuable as they constitute aquifers, or as in the case of gravels and sands, are used as construction materials. The Quaternary deposits are the fill of valleys that are now buried. The buried valleys of Tallinn are carved into older rock likely by ancient rivers to be later modified by glaciers. While the valley fill is made up of Quaternary sediments the valleys themselves originated from erosion that took place before the Quaternary. The substrate into which the buried valleys were carved is made up of hard sedimentary rock of Ediacaran, Cambrian and Ordovician age. Only the upper layer of Ordovician rocks protrudes from the cover of younger deposits, cropping out in the Baltic Klint at the coast and at a few places inland. The Ordovician rocks are made up from top to bottom of a thick layer of limestone and marlstone, then a first layer of argillite followed by first layer of sandstone and siltstone and then another layer of argillite also followed by sandstone and siltstone. In other places of the city, hard sedimentary rock is only to be found beneath Quaternary sediments at depths reaching as much as 120 m below sea level. Underlying the sedimentary rock are the rocks of the Fennoscandian Craton including gneisses and other metamorphic rocks with volcanic rock protoliths and rapakivi granites. These rocks are much older than the rest and do not crop out anywhere in Estonia.
