Question: How far from the Baltic Sea is Koporye located?
Context: Estonia ( ; Estonian: "Eesti" ), officially the Republic of Estonia (Estonian: "Eesti Vabariik" ), is a country in the Baltic region of Northern and Eastern Europe.  It is bordered to the north by the Gulf of Finland, to the west by the Baltic Sea, to the south by Latvia (343 km), and to the east by Lake Peipus and Russia (338.6 km).  Across the Baltic Sea lies Sweden in the west and Finland in the north.  The territory of Estonia consists of a mainland and 2,222 islands in the Baltic Sea, covering 45339 km2 of land and water, and is influenced by a humid continental climate.  Ethnic Estonians are a Finnic people, sharing close cultural ties with their northern neighbour, Finland, and the official language, Estonian, is a Finno-Ugric language closely related to Finnish and the Sami languages, and distantly to Hungarian. Estonia is a country in the Baltic region of Northern Europe.  It is bordered to the north by the Gulf of Finland, to the west by the Baltic Sea, to the south by Latvia (343 km), and to the east by Lake Peipus and Russia (338.6 km).  Across the Baltic Sea lies Sweden in the west and Finland in the north.  The territory of Estonia consists of a mainland and 2,222 islands and islets in the Baltic Sea, covering 45339 km2 of land, and is influenced by a humid continental climate. The Baltic Sea Campaigns were conducted by Axis and Allied naval forces in the Baltic Sea, its coastal regions, and the Gulf of Finland during World War II.  After early fighting between Polish and German forces, the main combatants were Germany and Finland, opposed by the Soviet Union.  Sweden's navy and merchant fleet played important roles, and the British Royal Navy planned Operation Catherine for the control of the Baltic Sea and its exit choke point into the North Sea.  While operations included surface and sub-surface combat, aerial combat, amphibious landings, and support of large-scale ground fighting, the most significant feature of Baltic Sea operations was the scale and size of mine warfare, particularly in the Gulf of Finland.  The warring parties laid over 60,000 naval mines and anti-sweep obstacles, making the shallow Gulf of Finland one of the most densely mined waters in the world. This is a list of islands in the Baltic Sea.  The Baltic Sea proper is bordered to the north by the Bothnian Sea and, further north, the Gulf of Bothnia, neither being part of the Baltic Sea proper.  The eastern basins the Gulf of Finland and the Gulf of Riga are likewise not considered part of the Baltic Sea proper.  Whether islands situated in, or on the borders to, these basins (Åland Islands, Hailuoto and Kotlin) shall be included in the list is therefore a matter of definition. The Baltic Sea is a sea of the Atlantic Ocean, enclosed by Scandinavia, Finland, the Baltic countries, and the North and Central European Plain.  It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga, and the Bay of Gdańsk.  The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude.  A mediterranean sea of the Atlantic, with limited water exchange between the two bodies, the Baltic Sea drains through the Danish islands into the Kattegat by way of the straits of Øresund, the Great Belt, and the Little Belt. The Baltic Sea Action Group (BSAG) is an independent foundation that does concrete work on behalf of the Baltic Sea, one of the most polluted seas in the world.  BSAG is based in Helsinki, Finland but it operates throughout the entire Baltic Sea area. Līva (German: "Lyva, Lyua, Libau" ) was a famous river in Kurzeme in today's Latvia.  It was located between the Baltic Sea and Liepāja Lake and had a length of about 6 kilometres and a width near the mouth of about 50 metres.  The source of the Līva was located in Liepāja Lake near the former Pērkone river.  The place where the Līva fell into the Baltic Sea was located approximately at the site of today's northern harbour in Liepāja.  The river had one known island, Perkunen (Latvian: "Pērkona galva" ); it was located near the source of the river.  The Līva served as a water trade way to Grobiņa via the Liepāja lake and the port was located on it.  The original suburb with a name Līva was located about 1 kilometre from the mouth of the river on both sides of it.  The old name for the city Liepāja descends from the name of the river and for the centuries was associated with it.  The part of the river near the mouth had become too shallow by the end of the 15th century.  In the 16th century, the first Līva channel was dug up between Līva and Baltic Sea with a length of about 780 metres and a width of 50 metres.  In 1697–1703, the new Trade channel was dug up and few years later the river was filled up. The Baltic Sea Parliamentary Conference (BSPC) was established in 1991 as a forum for political dialogue between parliamentarians from the Baltic Sea Region.  BSPC aims at raising awareness and opinion on issues of current political interest and relevance for the Baltic Sea Region.  It promotes and drives various initiatives and efforts to support a sustainable environmental, social and economic development of the Baltic Sea Region.  It strives at enhancing the visibility of the Baltic Sea Region and its issues in a wider European context. Koporye (Russian: Копорье ; Finnish: "Kaprio"; Swedish: "Koporje" ) is a historic village ("selo") in Leningrad Oblast, Russia, located about 100 km to the west of St. Petersburg and 12 km south of the Koporye Bay of the Baltic Sea.  It contains some of the most impressive medieval ruins in Russia. There are over 200 ports in the Baltic Sea.  When only those ports that handle minimum of 50,000 tonnes of cargo annually, and where at least part of this cargo is international, are taken into account the number of ports reaches approximately 190.  In 2008, the total amount of cargo handled in the Baltic Sea ports amounted to 822.4 million tonnes, which is 0.4 per cent less than in 2007.  Primorsk, Saint Petersburg and Muuga were the biggest ports in the Baltic Sea in 2008.  Together the three top ports handled over one fifth of total cargo volumes in the Baltic Sea in 2008.
