Poland; its main house of worship is the Holy Trinity Church from 1782, one of Warsaw's most important and historic landmarks. The Evangelical Reformed Parish (Calvinist) is leading the Polish Reformed Church. The main tserkva of the Orthodox Christians is Praga's Cathedral of St. Mary Magdalene from 1869. The Jewish Commune of Warsaw (Gmina Wyznaniowa Żydowska) is one of eight in the country; Chief Rabbi of Poland Michael Schudrich resides in the city. There are also 3 active synagogues, one of which is the pre-war Nożyk Synagogue designated for Orthodox Jews. An Islamic Cultural Centre in Ochota and a small mosque in Wilanów serve the Muslims. Government and politics As the capital of Poland, Warsaw is the political centre of the country. Almost all central government institutions are located there, including the Chancellery of the President, both houses of the Polish Parliament (the lower house called Sejm and the upper house called Senate), the Chancellery of the Prime Minister, the Constitutional Tribunal, the Supreme Court, and the Supreme Administrative Court. The city is represented in the parliament by 20 members of Sejm (out of 460) and 4 senators (out of 100). In addition, Warsaw elects together with its metropolitan area two MEPs (Members of the European Parliament). Municipal government The first city mayor of Warsaw was Jan Andrzej Menich (1695–1696).

In the years 1990–1994, the city mayor of Warsaw was elected by the city council.

During this period, the mayor of gmina Centrum who was elected by its council was automatically designated as the city mayor of Warsaw, in spite of representing only a fraction of the population of the city. The city was becoming increasingly unmanageable, especially after the administrative reform of Poland in 1999 which further complicated the local government structure of Warsaw. In 2002, the new Warsaw Act of the Polish parliament restored Warsaw as a
