Historical outline
The village of Rumno (formerly also called "Hrumno") was first mentioned as early as in the 15th century. Over the centuries it belonged to the families of Kol, Mielec, Ostroróg, Wiśniowiecki, Ogiński, Prota Potocki, Kajetan Skopowski and finally to the Lanckorońskis, who remained the owners until 1939.

. The foundation of the Roman-Catholic parish took place in 1471. According to very scarce information, in the first half of the 17th century the existing temple was taken care of by Bernardine monks. In 1648, a Cossack invasion took place, burning down the monastery and most probably the church. In the same century a school was opened in the parish. In 1734 the construction of a new wooden church of St Catherine was initiated. In the 18th century, the parish included such villages as: Horożana Wielka, Horożanka (Horożana Mała), Nowosiółki (Opawskie), Podwysokie, Rumno, Ryczychów and Saska (Dominikalna) and this composition lasted (probably) until the Second World War. In the same century, a hospital functioned on the parish grounds. In the 19th century, the confraternities of the Holy Trinity and the Sacred Heart of Jesus were active at the church. In 1934, the construction of a new brick church was initiated. In 1940, the work was completed and the old building was demolished. In 1946, the Soviet authorities ordered the demolition of the brick building together with the old bell tower.

Architecture
There is not much information about the old church. What is known for sure is that it was an oriented building (i.e. facing east, implying Jerusalem), wooden on a stone foundation.

The new church was situated to the south-west of the old one, built of brick but not plastered, with the chancel facing south. It had a three-nave, basilican, four-bay body. The chancel was short and closed triangularly with an attached rectangular vestry. There was a rectangular porch at the front. The windows in the nave section were circular. The chancel was rectangular, closed with a semicircle, except for the wall behind the altar. It too had circular openings, identical to those in the nave.

The façade was crowned with a triangular gable. The façade of the porch ended in a similar manner. The articulation of the side walls of the body was made with lisens closed with a profiled cornice. The nave, chancel and (probably) the sacristy were covered with gable roofs, and the side aisles with pent and multi-pitched roofs. All were covered with sheet metal, except for the gabled roof over the porch. This was decorated with tiles. The metal-clad bell tower was octagonal in shape. It was topped with an openwork lantern with a conical roof topped with a cross.

The most important elements related to the church furnishings and surroundings were:

• The main altar dating from the 19th century;
• The bell tower dating from 1794, which was located to the north-east of the old church.

Jerzy T. Petrus, in his study of the buildings, makes it clear that they have not hitherto attracted the interest of art historians, although at the beginning of the 20th century the old church was one of the few surviving examples of wooden Latin churches in the area.
