The chateau church, in the form of a high rotunda covered with a cupola and preceded by a monumental eight-column portico, is situated at the end of a tree-lined avenue leading to the chateau. This created a picturesque axial arrangement based on the line park - fortified palace - church. It is worth noting the colonnaded portico topped with sculptures and a triangular pediment, considered the first example of Classicist architecture in Polish sacral architecture. In this way, it preceded by 40 years similar works designed by Piotr Aigner for Warsaw, Puławy and Żyrzyna, and referring to the Roman Pantheon.

The interior of the temple was covered with an illusionist polychrome made in the main parts by the painters Łukasz Smuglewicz (1709-1780) and his son Antoni (1740-1810). The work was completed in 1763. The frescoes, which have been preserved to this day, are of a high artistic class, the colours are bright and vivid, with a predominance of greens and pinks. The illusionistic architectural elements are marbled and the details are gilded. In addition to the painted architecture, the representations of the four cardinal virtues painted above the windows stand out: Fortitude, Prudence, Justice and Temperance, and medallions supported by putti with busts of St Joseph and St Anne.
