Baroque architecture was introduced in the Republic by monasteries associated with the post-Tridentine renewal. Particularly important was the activity of religious architects from Italy. The Jesuit Giovanni Maria Bernardoni, an architect and builder who worked in Poland between 1583 and 1605 at the invitation and commission of the Polish Jesuit provincial, also worked for individual clients - among them Mikołaj Krzysztof Radziwiłł 'Sierotka'.

This magnate founded the Corpus Christi church and Jesuit college in Nesvizh, one of the first Baroque and Jesuit churches in the former Polish-Lithuanian Commonwealth, built in 1587-1593 on the model of the Roman temple Il Gesù.

The church was designed on the plan of a Latin cross, as a three-nave church with galleries over the side aisles (now non-existent), with a semi-circular apse and a cupola at the intersection of the transept and the nave, with a partial basement. The façade was clearly inspired by Roman solutions. A cemetery was established on the church grounds and a bell tower and rectangular chapel were built in two opposite corners. The church compound also received a fence. Under the church there is a vaulted crypt, in which more than 100 members of the Radziwiłł family are buried.

In autumn 2006, under the direction of Dr Ryszard Jurkiewicz, the foundations and crypts of the Corpus Christi church were dried and waterproofed. Funding was provided within the framework of the Programme of the Minister of Culture and National Heritage at the request of the Ciechanowieckie Name Collections Foundation.
