The atmosphere of the town is unique, partly due to the split between its old and new sections, which are so explicitly separated from each other. As Sandomierz suffered relatively little damage during the two world wars, the remnants of its enormously rich 10-century long history survives to this day in their original form. The density of architectural and artistic gems is remarkable in an area so small. Most of them are located in the Old Town, set in almost rural surroundings. Worth seeing are the Market Square with its Gothic Cathedral and 14th century Gothic Town Hall, later redesigned in the Renaissance style; the 14th century Gothic Castle and Diocesan Museum full of curiosities. Sandomierz is a significant centre of religious activity with four historic churches located within this small town.

One very unusual attraction of Sandomierz is its underground passages, measuring some 470 m in length and going round the Gothic cellars of the local traders. Interesting sites near Sandomierz include Baranow Sandomierski (a small town famous for its castle nicknamed “Little Wawel”) and the Pepper Mountains with its 18-hectare nature reserve, from which one can delight in a panoramic view of Sandomierz.
