Historical outline
Miżyniec is situated only 16 km south-east of Przemyśl. The village was first mentioned as early as the 14th century. It is said that a parish was established here at the beginning of that century, but its historical origins are not entirely clear. However, it is almost certainly known that an independent parish functioned here in the 15th century. Later owners include a certain Jasiek, the Deriniaks from Rokitnica, Abraham Herburt, the Korniakts, the Krasińskis, the Mniszeks and the Lubomirskis. The last owners of the estate were the daughters of Franciszek Lubomirski: Jadwiga Świeżawska and Zofia Humnicka.

Of the most important points in the history of the church and the parish, the consecration of 1642 should be mentioned first and foremost, which crowned the restoration of the building. At the same time, the vicarage, parish school and hospital were renovated. Unfortunately, a fire in 1696 destroyed the first wooden incarnation of the church. It was replaced by another, funded by Anna Baranowska of Tęczyn. In 1721, the church was covered with a new roof. The building had a brick crypt and a newly erected bell tower with two bells. At the end of the 18th century, the Holy Trinity Confraternity functioned within the church, which lasted for more than a century, operating alongside the Confraternity of the Sacred Heart of Jesus, the Rosary and the Abstinence. The minutes of 1741 describe the church as 'old, wooden and still unconsecrated'. It is likely that this condition was the impetus for the erection of a new, this time brick building, which was completed in the early 1770s thanks to the foundation of Adam Józef Mniszek, Crown Ensign. In 1772 it was consecrated by Father Jacek Rogowski. From then until the First World War, not much information was recorded about the building. The church suffered structural damage during the war effort and, in addition, two bells were confiscated by the Austrian authorities in 1916. After the war, renovation was undertaken, although sources note that this took a long time, as the condition of the building still left much to be desired in 1927.

As Andrzej Betlej writes in his study of the building, after the Second World War the church was served once a month by a priest from Nowe Miasto. In 1959, however, it was finally closed. It returned into the hands of the faithful in 1989, at which time an extensive renovation was carried out. At present, the following villages belong to the parish: Deżyce, Zrotowice, Drozdowice, Wielunice, Stroniowice, Tyszkowice, Bojowice, Horysławice, Rostysławice, Boracice, Cyków, Popowice, Chidnowice.

Architecture
The oriented (i.e. facing east, by implication towards Jerusalem), brick and plastered church was situated on a hillside. It consists of a two-bay nave and a two-bay chancel, slightly smaller than the main body. Adjoining it is a square Lubomirski burial chapel with an independent additional chancel of its own. In front of the nave part there is a square porch.

In the chapel, a rectangular window closed with a semicircle. All other window openings are rectangular, closed with a segmental arch. The door openings have a similar shape, except in the chapel. There the doors were closed with a semicircular arch. The wooden music choir was supported by two pillars. It is accessed via a circular staircase in the north-west corner of the church.

The exterior walls have articulation built on Tuscan pilasters. This articulation takes its most sublime form on the façade side. Here, the ornamentation of the individual elements is enhanced by additional veiling. The façade is based on a single storey, but tripartite. Like the rest of the building's walls, it is divided by Tuscan pilasters, with the difference that they are doubled on both sides in the central part and doubled on the outside at the corners. In the lower part there is a porch, in terms of decoration, which is a graceful echo of the whole. In other words, it is surrounded by proportionally smaller pseudo-pillars, and the entrance opening has been enclosed in a frame.

Above the porch is a deeply set window, enclosed by a slight embellishment. In the side fields, paintings of the saints have been placed in panels. The top of the façade is in the form of a wide aedicula, consisting of pseudo-pillars and a triangular abutment. In the centre is a painting of Our Lady of the Angels. The nave and chancel were surmounted on the east by triangular gables, which was probably intended to correspond with the finial of the façade. A circular window was placed in the chancel gable.

The nave and chancel have gable roofs, the vestry has a pent roof and the porch has a marquee roof. In turn, there is a tent roof (gable) over the chapel. All covered with sheet metal. The octagonal turret is also covered with sheet metal and topped with a conical cupola with a cross.

Inside, the paintings are particularly noteworthy. Both on the walls and on the vaults. These are late Baroque works, dating from around 1772. Researchers unequivocally stress that the current shape of the church is far from the original, noting that it is difficult to establish any specific point of reference. The current state of the building's architecture is the result of a reconstruction that probably took place at the turn of the 19th and 20th centuries. Changes made after the First World War may have had an additional impact. Therefore, the primary value of the church, for a long time, has been the paintings. Unfortunately, when the church was returned to the congregation, it was in poor condition due to damaged roofs and dampness penetrating the interior.

Highlights of the building's furnishings and surroundings include:

• Numerous 18th and 19th century paintings of saints;
• Tabernacle (18th century): wooden, architectural, painted and gilded;
• Neo-Baroque pulpit made by the workshop of Ferdinand Majerski of Przemyśl;
• 18th century baptismal font decorated with festoons and rocaille ornaments;
• 18th century confessionals.
