Toompea in the context of "Riigikogu"

St. Mary's Cathedral (Estonian: Toomkirik, German: Ritter- und Domkirche, full name: The Episcopal Cathedral of the Holy Virgin Mary, Tallinn, Estonian: Tallinna Püha Neitsi Maarja Piiskoplik Toomkirik) is a Lutheran cathedral church located on the Toompea hill in the medieval central part of Tallinn, the capital city of Estonia. Established in the 13th century, it is the oldest church in Tallinn and mainland Estonia, and the only building in Toompea which survived the 17th-century fire.

The church was originally established in the 13th century as the Roman Catholic cathedral, after Tallinn and northern Estonia had been conquered by the Kingdom of Denmark during the Northern Crusades. In the aftermath of the Protestant Reformation, the church became Lutheran in 1561 and is now seat of the Archbishop of Tallinn, the spiritual leader, and chairman of the governing synod, of the Estonian Evangelical Lutheran Church.

An academy of sciences is a type of learned society or academy (as special scientific institution) dedicated to sciences that may or may not be state funded. Some state funded academies are national, or royal (i.e. United Kingdom's Royal Society of London for Improving Natural Knowledge) as a form of honor.

The other type of academies are Academy of Arts or combination of both (e.g., American Academy of Arts and Sciences).Academy of Letters is another related expression, encompassing literature.In non-English-speaking countries, the range of academic fields of the members of a national Academy of Science often includes scholarly disciplines which would not normally be classed as "science" in English. Many languages use a broad term for systematized learning which includes both natural sciences and social sciences and fields such as literary studies, linguistics, history, or art history. (Often these terms are calques from Latin scientia (the etymological source of English science) and, accordingly, derivatives of the verb 'know', such as German Wissenschaft, Swedish vetenskap, Hungarian tudomány, Estonian teadus or Finnish tiede.) Accordingly, for example the Austrian Academy of Sciences (Österreichische Akademie der Wissenschaften), the Hungarian Academy of Sciences (Magyar Tudományos Akadémia), or the Estonian Academy of Sciences (Eesti Teaduste Akadeemia) also cover the areas of social sciences and humanities.

Founded in 1938, the Estonian Academy of Sciences (Estonian: Eesti Teaduste Akadeemia, Latin: Academia Scientiarum Estoniae) is Estonia's national academy of science in Tallinn. As with other national academies, it is an independent group of well-known scientists whose stated aim is to promote research and development, encourage international scientific cooperation, and disseminate knowledge to the public. As of March 2017, it had 77 full members and 20 foreign members. Since 15 October 2014, the president of the Academy is the mathematician Tarmo Soomere.
