The Vistula (/?v?stj?l?/; Polish: Wisła ?viswa) is the longest and largest river in Poland, at 1,047 kilometres (651 miles) in length. The drainage basin area of the Vistula is 194,424 km2 (75,068 sq mi), of which 168,699 km2 (65,135 sq mi) lies within Poland (splitting the country in half). The remainder is in Belarus, Ukraine and Slovakia.
The Vistula rises at Barania Góra in the south of Poland, 1,220 meters (4,000 ft) above sea level in the Silesian Beskids (western part of Carpathian Mountains), where it begins with the White Little Vistula (Biała Wisełka) and the Black Little Vistula (Czarna Wisełka).1 It then continues to flow over the vast Polish plains, passing several large Polish cities along its way, including Kraków, Sandomierz, Warsaw, Płock, Włocławek, Toruń, Bydgoszcz, Świecie, Grudziądz, Tczew and Gdańsk. It empties into the Vistula Lagoon (Zalew Wiślany) or directly into the Gdańsk Bay of the Baltic Sea with a delta and several branches (Leniwka, Przekop, Śmiała Wisła, Martwa Wisła, Nogat and Szkarpawa).

Worth to visit
Kraków's historic centre, which includes the Old Town, Kazimierz and the Wawel Castle, was included as the first of its kind on the list of UNESCO World Heritage Sites in 1978.72 The Stare Miasto is the most prominent example of an old town in the country.73 For many centuries Kraków was the royal capital of Poland, until Sigismund III Vasa relocated the court to Warsaw in 1596. The whole district is bisected by the Royal Road, the coronation route traversed by the Kings of Poland. The Route begins at St. Florian's Church outside the northern flank of the old city-walls in the medieval suburb of Kleparz; passes the Barbican of Kraków (Barbakan) built in 1499, and enters Stare Miasto through the Florian Gate. It leads down Floriańska Street through the Main Square, and up Grodzka to Wawel, the former seat of Polish royalty, overlooking the Vistula river. Old Town attracts visitors from all over the World. Kraków historic centre is one of the 13 places in Poland that are included in the UNESCO World Heritage Sites. The architectural design of the district had survived all cataclysms of the past and retained its original form coming from the medieval times. The Old Town of Kraków is home to about six thousand historic sites and more than two million works of art.74 Its rich variety of heritage architecture includes Gothic, Renaissance and Baroque buildings.
