The building is remarkable for its impressive shape and the abundance of works of art. Among others, you can find here: an 18th-century painting of Mother of God with the Child, the Mournful Christ in clothing from the 18th C. and a 15th-century crucifix. All of them used to be the objects of exceptional cult. The cathedral is a Gothic hall-temple with cross and rib vaulting and interesting keystones with heraldic ornamentation. The cornices are covered with floral and animal motifs, which enlivens the inside. In the presbytery there are Byzantine-Ruthenian frescos, depicting the scenes from the life of Jesus and Virgin Mary. They come from the period of king Władysław Jagiełło’s reigns and the series is one of four of such type in Poland. The church furnishing is mostly Baroque. The most popular piece is a cycle of 16 paintings, known as the “Martirologium Romanum” – it is a visionary depiction of the death of the Roman and Sandomierz martyrs. The composition of altars and stalls in the naves is quite notable too - a set of 8 altars from the 70s of the 18th C. is the work of Maciej Polejowski, a sculptor and architect of a famous family from Lvov. The main altar also comes from the 18th C. and is made of marble; in its central part there is a picture of the Blessed Virgin Mary’s Nativity, painted by Józef Buchbinder (a student of Jan Matejko), above there is a wood-carved image of the Holy Trinity.

The Church of St. Jacob – the oldest, most cameral and most often visited
The Church of St. Jacob belongs to the most beautiful and oldest objects of this royal town. It was built in 1226 by bishop Iwo Odrowąż who decided to bring the Dominican Order and since then the monks have resided in here. The temple is a Romanesque sacral building, unique on the scale of the whole country. It is also one of the first churches made of brick and richly ornamented. The most remarkable element  of the structure is an astonishing Romanesque portal with a bipartite entrance made of fired brick - such elaborate portals were supposed to encourage the people to enter the temple. Architecture amateurs will certainly be amazed by the shape of the building and in the ascetic inside there are remarkable works of art. One of them is a tomb of princess Adelajda (Adelaide), carved in oak-wood - her remains rest in a brass coffin. Another one is the Chapel of Martyrs - on its wall there is a Baroque painting of Karol de Prevost, depicting a martyr’s death of 49 monks. They, and many other citizens, died from the hands of the Mongolians on the 2nd of February 1260, yet earlier they are said to have heard a prophecy of their own death… In the northern nave one can even see the remains of the murdered and some arrowheads from that time, discovered during the archeological works in the area of the church cloisters. There are also other historic pieces, like epitaphs, tombs, sculptures, paintings and stained-glass windows. Bearing in mind the history of the place, one watches all these with excitement.
