Cathedral of Saint Bonaventure, Roman Catholic cathedral in Banja Luka, Bosnia and Herzegovina

The Cathedral of Saint Bonaventure is a modern church building with white exterior walls and a prominent bell tower that was completed in 1973. The structure houses five bells and provides space for services and visitors.

Fra Marijan Marković laid the foundation stone of the first cathedral on 16 July 1884, and it was completed in 1887 at a cost of 26,000 florins with help from the Trappists of Marija Zvijezda. That building was severely damaged in the 1969 earthquake and had to be demolished. The present cathedral was built on the same site in 1973, its bell tower finished in 1990, and it was thoroughly renovated and reinaugurated in 2001 for the 120th anniversary of the diocese.

The cathedral serves as the principal place of worship for the Roman Catholic community of Banja Luka and hosts regular religious gatherings. The building anchors the spiritual life of Catholics in the region.

The building is located centrally in Banja Luka and is easily accessible on foot. Visitors should observe religious etiquette, especially during services, and wear appropriate clothing.

The interior holds the tomb of Marijan Marković, a significant local religious figure. This burial makes it a place of special importance to the Catholic history of the region.
