The Neo-Romanesque style in Polish religious architecture has not yet attracted much interest from researchers. This article is the first attempt to present this topic. Since the second quarter of the last century, we have sporadically attempted to design in Byzantine styles, which were considered to belong to the early phase of the Romanesque period. Russian Orthodox architecture resulted in a reluctance to expose Eastern elements in the design of Catholic churches. It should also not be forgotten that for some time the terms Romanesque and Byzantine styles were considered synonyms, and in the early 1940s the term "Lombard style" appeared. Its shapes originally refer to the so-called arcade style, called "round arch style" in Prussia. Over time, the term "Lombard style" was narrowed down to the medieval architecture of northern Italy, and from the second half of the 19th century, French and German patterns dominated. They were available in two versions: traditional, with plastered external walls, and a new one - the so-called conch shell. The attractiveness of this Neo-Romanesque version resulted from the far-reaching reduction of the decorative program - in line with the general assumptions of this style. Attention should also be paid to the syncretic direction, commonly called the "transitional style": Romanesque-Gothic. After a period of relative popularity in the last quarter of a century, the genre begins to die out at the threshold of the new century, from the beginning of the 20th century. One can notice attempts to break free from the canons of aesthetics that have already become anachronistic. The work uses stylized Romanesque motifs with national features added. However, these Neo-Romanesque attempts are dominated by the cosmopolitan Neo-Romanesque style, sometimes subjected to modernization.
