Nowy Sącz is a town in the Lesser Poland Voivodeship in southern Poland. It is the district capital of Nowy Sącz County.

The town Nowy Sacz has many historic features, including: (From Wikipedia)

One of the largest marketplaces in Europe, after Kraków, the largest rynek in Poland. The late 19th century Ratusz (city hall) is centered in the square.

Saint Margaret's basilica, Bazylika kolegiacka Św. Małgorzaty (15th century). 

A 15th-century house Dom Gotycki containing a regional museum.

A gothic Franciscan church.

The Great Synagogue, dating from 1746, now the Galeria Dawna Synagoga, a gallery with some historical displays.

Saint Roch, a church of wooden construction from the 15th century, in the Dąbrówka district. The old cemetery chapel St. Helen's Church is another example.

The partially restored ruins of a mediæval Royal Castle from the 14th century during the reign of Kazimierz the Great.

The mountainous country around Nowy Sącz is also popular with tourists, hikers and skiers, especially the Beskid Sądecki mountains (part of the Carpathians), of which the highest peak is Radziejowa (1,262 m (4,140.42 ft) above sea level).

Looks like very nice town in Poland. I would like to visit one day.
