Warsaw, the capital of Poland, is located in the very centre of Europe. It stands on the Vistula River in east-central Poland, roughly 260 kilometres (160 mi) from the Baltic Sea and 300 kilometres (190 mi) from the Carpathian Mountains. Its population is officially estimated at 1.750 million residents within a greater metropolitan area of 3.101 million residents, which makes Warsaw the 9th most-populous capital city in the European Union.
The city is the seat of the Polish Academy of Sciences, Warsaw National Philharmonic Orchestra and the University of Warsaw. The historic city-centre of Warsaw with its picturesque Old Town in 1980 was listed as a UNESCO World Heritage Site. Other main architectural attractions include the Castle Square with the Royal Castle and the iconic King Sigismund's Column, St. John's Cathedral, Market Square, palaces, churches and mansions all displaying a richness of colour and architectural detail. Buildings represent examples of nearly every European architectural style and historical period. Warsaw provides many examples of architecture from the Gothic, Renaissance, Baroque, neoclassical and modern periods, and around a quarter of the city is filled with royal parks and lush gardens.
