Warsaw (Polish: Warszawa) is the capital and largest city of Poland. It is located on the Vistula River roughly 360 kilometers (224 mi) from the Baltic Sea and 300 kilometers (186 mi) from the Carpathian Mountains. Its population as of June 2009 was estimated at 1,711,466, and the Warsaw metropolitan area at approximately 2,785,000.[1] The city area is 516.9 square kilometers (199.6 sq mi), with an agglomeration of 6,100.43 square kilometers (2,355.4 sq mi) (Warsaw Metro Area – Obszar Metropolitalny Warszawy). Warsaw is the 9th largest city in the European Union by population. Warsaw is one of the Alpha Cities.

Warsaw's mixture of architectural styles reflects the turbulent history of the city and country. During WWII, Warsaw was razed to the ground by bombing raids and planned destruction. After liberation, rebuilding began as in other cities of the communist-ruled PRL. Most of the historical buildings were thoroughly reconstructed. However, some of the buildings from the 19th century that had been preserved in reasonably reconstructible form were nonetheless eradicated in the 1950s and 1960s (e.g. Leopold Kronenberg Palace). Mass residential blocks were erected, with basic design typical of Eastern bloc countries.
