The city of Bielsko-Biala is situated on the Biala River, with the formerly German-speaking town of Bielsko on the left bank, and the smaller Polish community of Biala located on the east bank. Bielsko-Biala is well-known for its Art Nouveau architecture, and is sometimes referred to as the 'Little Vienna' of Poland. Sights include the formidable 16th-century Bielsko Castle, home of the Sulkowski princes; the Frog House, an ornate mansion featuring, you guessed it, statues of frogs over the entryway; the Weaver's House, a noteworthy example of craftsman architecture; and multiple ski resorts located in the Silesian Beskids mountain range. As a matter of fact, it is home to a small but visible Jewish community, which before the Holocaust comprised about a fifth of the city's population.
