Historical outline
Pnikut was also called Pnekolt, Pnekot and sometimes Pnikult in the past. The oldest mention of the village dates back to the 14th century. The first information about the local parish appears at the height of the next century. The owners of the estate include: Piotr Radziejewski, Chlipel and Zachariah Szulżyc, Michał Myszka, Piotr Stryjski and the Bishops of Przemyśl, to whom Pnikut was bequeathed, but the exact origins are not fully known. It is also unknown when the first religious building in the village was erected. There are, however, a number of records of successive (wooden) buildings which were erected, repaired and consecrated over the centuries.

At the beginning of the 20th century, however, it was decided to build a modern masonry church in the village, as the needs of the worshippers had long exceeded the available, but much too small and damaged by time. The church was consecrated in 1912, but unfortunately, three years later, during World War I, the church suffered damage and, in addition, the military authorities confiscated the bell the following year. The old wooden church was also damaged and it was finally decided to demolish it in 1920. A year later, the renovation of the brick church was completed and it was consecrated again.

The inter-war period was a time of some modernisation. Among other things, new bells were added to the church. The Second World War brought no destruction, but in 1946, the last parish priest left the parish and went to Przemyśl. The faithful, however, did not let the temple out of their hands. For almost the entire post-war period, the local community took care of the building, using it officially and legally as a "chamber of culture". At stake were the huge taxes it had to pay. As Piotr Krasny writes in his study of the building, until the parish was reconstituted in 1989, the faithful met in the church and held all possible services that did not require the presence of a priest. In 1993, largely thanks to the generosity of parishioners and benefactors from Poland, a new vicarage was built.

Architecture
The building is situated on the road from Mosciska to Krukienice, in the middle of the village on a small hill. The presbytery faces west. The contemporary 20th-century church was built of brick with concrete in the structural parts. The overall character of the building is neo-Gothic designed with unusual balance. According to Piotr Krasny, the building is one of the most magnificent early 20th century churches in the eastern part of the Przemyśl diocese.

The body of the temple is hall-shaped, three-nave and three-bay. The chancel, closed trilaterally, is lower and narrower than the nave. As was typical of many buildings in this style at that time, the whole is fronted by a square tower. In its ground floor there is a porch. On either side of the tower on the ground floor are rectangular annexes containing a staircase and a treasury. Similar annexes are located on the side of the presbytery. They house the sacristy and the treasury.

In the external façade, the most striking feature is the arcaded frieze and the plaster plinth below. Windows in neo-Gothic style. Mostly rectangular, closed at the top with a sharp arch. The tower and chancel are lit by round windows, or oculus. The window openings in the tower annexes are also an exception. Here, narrow windows reminiscent of gunposts are used.

The naves of the body were separated by cross pillars, while the articulation of the walls was carried out with Tuscan pilasters. The building is dominated by cross-ribbed and star vaults. A crystal vault is used in the porch, while ceilings are used in the side rooms. The choir has the form of a concrete balcony built into the first bay of the body. It is supported by four columns decorated in capitals.

The body and chancel are covered by gable roofs. There is a multi-pitched roof over the apse, and pent roofs were used over the vestry, vault and annexes. All of them are covered with sheet metal, as is the cupola of the tower, which has the shape, typical of neo-Gothic buildings, of a high pyramid, topped in this case with a cross. The turret of the bell tower is also covered with sheet metal.

Highlights of the church furnishings and surroundings include:

• A single wooden ensemble comprising: three altars, pulpit, stalls, supper bench, balustrade separating the chancel and confessionals, dating from the early 20th century;
• Main altar, comprising three chapels;
• Altar of St. Nicholas;
• St Casimir's altar;
• Paintings: "St. Nicholas" dated to the 18th century, "St. Joseph with Child and Angel" dated to the 18th century, "Vision of St. Anthony" dated to the 19th century, "Our Lady Immaculately Conceived" dated to the 18th century;
• The sculpture "Christ Crucified" dated to the 18th century.
