Before the tragic events of September 9th and 10th, 1943, the Parish Church of The Cross (Župna Crkva Nasašće Sv. Kriza) stood as an imposing sight in the southern part of the town, nestled near the two schools and the council building. It had been the site of a church for hundreds of years.

In 2013, the Sisak Diocese reported the discovery of a monumental Gothic Church in Zrin. The research, commissioned by the Diocese of Sisak and conducted by the City Museum of Sisak in cooperation with the Diocese's Culture Office, revealed a grand single-nave Gothic church with a round apse and reinforced buttresses from pre-Turkish times. The figures showed that this was a significant discovery. Thus, the size of the foundation indicated that the length of the church was 28 meters, the width of the nave was 14 meters, and the widest part, including the sacristy and the bell tower, was 19 meters. It was stated that the size of this stone building testified to the importance of Zrin itself in the medieval history of Croatia.

Currently, a newly built church stands on a block of land next to the old Church site. The old Church had three entrances: one on the northwest side, on the driveway that led from the school; the second was on the southwest side where there was a bench under a plain tree—the tree still stands and provides beautiful shade on hot summer days. In the old days, people used to sit on the bench, waiting for Mass to begin. On the side where the sacristy was located, there was also a third entrance for the Priests.

This church boasted a belfry with three bells. The floor was made of stone, and there was an organ and choir loft in the church. Its walls were adorned with pictures depicting the Stations of the Cross, and an elderly villager recalled a fresco on the ceiling above the main altar. Further research indicated that during the Baroque period, a flat ceiling, known as a tabulat, was constructed over the sanctuary and nave, painted by the renowned Zagreb artist Makovec in 1740.

Within the church, three altars graced the space—one on the left, one on the right, and the main altar in the centre. Masses were celebrated on Feast Days and every Sunday. Regarding seating arrangements, women occupied the pews on the left side of the church, while men sat on the right. There was a designated area for girls to stand, marked by a fence under the pulpit, while older men were seated in chairs.

A path made of stone slabs led from the main entrance of the church to the road, avoiding walking on dirt and grass. In the event of someone's passing, a small bell would ring. For farewells to the deceased and during Masses, all three bells would chime.

Today, in the new church, the bells ring at 6:00am, 12 noon and 7pm.
