Historical outline
The village is located about 20 km east of the city of Translate, on the right bank of the Dniester. Delawa was first mentioned as early as in the 15th century, when King Władysław Jagiełło granted the village to the rectory in the larger Koropiec, located 4 km to the south-east. The ownership of the estate lasted until the 20th century.

Parish ownership also continued until the 20th century. The village was subordinate to the parish in Koropec from its official beginning until the 1920s, when first an exposition was established here (1921) and four years later an independent parish. For this to succeed, a religious building was needed. Although there had been a chapel in the village for several centuries (built before 1721), it was inadequate. It served as an emergency function when the water level made it impossible for worshippers to reach Koropec.

As Catherine Brzezina cites in her study of the building, "it was a two-storey building 'made of oak cubed in triangle'(...). Inside was an altar 'elegantissima et pictura et structura', with images of Our Lady Immaculate (in the field) and St Stanislaus Kostka (in the finial)".

The parsonage was built at the height of 1921, and was converted from a small outbuilding.

The last caretaker of the parish was Father Antoni Warzynski. He managed to save some of the church furnishings when he left Delawa in the late 1940s. In 1950 the church was turned into a food warehouse by the communists and later into a mill. This required structural changes and the creation of additions. The building was therefore severely altered and devastated. There is information that another modernisation was carried out in 1997, but the church has not been returned to the faithful and today simply deteriorates.

At the time of its greatest activity, the parish had religious confraternities and associations such as the Living Rosary Association, the Catholic Husbands' Association, the Catholic Women's Association, the Catholic Male and Female Youth Associations and the Parish Catholic Action.

In the 20th century, traces of a Neolithic settlement were discovered in the village.

Architecture
The site is located in the eastern part of the village, on top of a hill. It is a stone-built, unplastered building with a chancel facing south-east. It consists of a nave and a narrower and lower chancel closed with a straight wall, behind which is the vestry.

The modern state of the building is much altered from the original. Therefore, when describing it, it is necessary to base the description on a vector based on design drawings from more than a century ago and old photographs, as well as those traces that can still be made out of the present state.

The facades of the building were made of irregularly worked stone. The whole was set on a plinth and braced by low buttresses. The façade, in its original and intact form, was tripartite with a central field framed by thick buttresses. It was crowned by a triangular gable with a Celtic cross. The front was dominated by a turret topped with a pyramidal roof surmounted by a cross. The side elevations were closed with a profiled cornice. The flat cornice, in turn, was run at the height of the window arches, creating a kind of frame.

The chancel, nave and vestry all have gable roofs, differing only in the nature of their abutments and pediments. A gable roof is placed over the vestibule of the sacristy. All are covered with zinc sheeting.

The interior has no articulation. The presbytery is covered with a barrel vault. The rainbow arcade is semicircular. The windows in the nave are rectangular, closed with a semicircle. In addition, the other window openings are either rectangular or rectangular closed with a segment. The wooden music choir, is currently in a state of complete devastation.
