The Church of Corpus Christi (Corpus Christi Church, the Jesuit church) - an architectural monument of the early Baroque - the first building of this style in the territory of the Polish-Lithuanian Commonwealth, was built in the end of the XVI century by the Italian architect Giovanni Maria Bernardoni at the expenses of the owner of Nesvizh Prince Radziwill Sirotka. The prototype of the church is a Roman temple Il Gesù, built in 1584 by architects Vignola and Porta. The church was built in conjunction with the Jesuit College.
The interior of the church has a lush decor. The main altar is decorated with the painting "The Last Supper" by the artist Heskey. Among the paintings of the church more than 40 compositions, are biblical legends.
Church decorated also by sculptures - altars of Jesus Christ and the Virgin Mary in marble and several monuments of memorial sculpture: monument to the founder of the temple Radziwill Sirotka and his children. A baby lying with folded hands on the lid of the coffin, covered with flowers - a monument to the first-born of Sirotka, died at the age of two. A large tombstone with a bust placed in memory of another son of Sirotka, who died at 16 years from the plague in Bologna. The third tombstone made of sandstone, was carried out after the death of the Sirotka. Here the founder of Nesvizh ordination is presented in the guise of a pilgrim praying on the background of knight's armor. Below the epitaph composed by Sirotka, which states that "In the face of death, no one is knight".
The temple is the ancestral burial place of the Radziwill family. In catacombs under the church, in tombs lie embalmed bodies of the Radziwill family of many generations. The first was buried here Sirotka in 1616. Nesvizh Radziwill family tomb - the only necropolis of the historical families in Eastern Europe.
One of the attractions of the church's court is "Bulgarin chapel" or "Tower of the murderer". It was built at the beginning of the XVIII century by Skanderbek Bulgarin. The history of this tower: after quarrel with a neighbor, Bulgarin killed him with a gun and was very sorry about this. According to the Lithuanian Statute, he had to pay the "Vira" and gave the family of the murdered several villages. And then he built a chapel and a few days alone, without food and water, to prayed for forgiveness for his sin and paid for 350 years ahead of the annual service for the dead.
