Historical outline
Nowoszyce lies approximately 18 km south-east of Sambor. The village was first mentioned as early as the 14th century. It is also known that in 1508 the village belonged to Hryćko Nowoszycki, and in 1589 to Agnieszka Pletycka and Adrian Kunat. In the 17th century it came back under the ownership of the Nowoszycki family again, but also of the Horodyski family. The village has always belonged to the parish of Dublany, but in the 1920s efforts began to establish a separate unit.

In the middle of the decade, a church was built on the initiative of Zofia (née Żółkiewska) and Włodzimierz Strzelecki, but the building itself is not everything. The consecration took place in 1926, but for the first few years the building stood empty. Finalising the formal matters seemed to be an essential act, although it took a long time.

The authorities were motivated not only by a religious vector, but also by a political one. According to Ewa Herniczek, "it is in the interest of consolidating and strengthening Polishness in this corner, surrounded by the Ukrainian element from all sides, to create a Roman Catholic parish as soon as possible". It was not until 1936 that a separate unit for the faithful was established, with the creation of a non-removable parish, which included Brodnica, Byki, Dorozhov, Luzhki Dolny, Ortynice and Prusy.

In 1938, it became apparent that the roof of the church was badly made, so the necessary repairs were undertaken. Unfortunately, the Second World War broke out a year later and the building was closed. It was used as a kolkhoz depot and warehouse until 1957. The equipment was probably transported to Sambor. At the end of the 1980s, a fire consumed the roof of the church and since then the building has deteriorated and remained a ruin.

Architecture
The church in Nowoszyce is a neo-Baroque building, characteristic of the 1920s. In some respects it resembles the designs of Wawrzyniec Dayczak. What draws attention in this respect is especially the facade similar to the church in Rudna. The building is situated on a hill, away from the village, on the road between Prusy and Nowoszyce. The single-span chancel with a semicircular apse faces north-east. It is narrower than the three-bay nave that forms the main part of the church. A vestry adjoins the chancel to the south-east. Most of the main windows are rectangular in shape, rounded at the top. There are oval and rectangular windows in the music choir and rectangular windows in the sacristy.

The façade is single-axis and single-storey. The attention is drawn to the tower, which rises from it on a square plan. It is, however, preceded by a picturesque gable with a concave-convex form with a round window opening. On the other side, above the presbytery and vicarage, there is a similarly rounded finial, but ending in a triangular gable. The helmet of the tower is bell-shaped, covered with sheet metal and topped with a wrought-iron cross. On the other side, there is also a cross in the finial above the chancel.

The side elevations of the nave and chancel are framed by buttresses and surmounted by a moulded cornice. The roofs over the nave, chancel and vestry are gabled. The roof of the apse, on the other hand, was designed in the form of a conical section. All were tiled. There is a cross on top of the chancel.
