Heilig-Kreuz-Kirche, Parish church in Bad Kreuznach, Germany.

The Heilig-Kreuz-Kirche is a neo-Gothic hall church of dark red sandstone, built 1895–1897 to plans by Mainz Cathedral master builder Ludwig Becker. It has three naves, a broad but short transept, narrow three-bay side aisles, and a tall slender bell tower set into the facade, flanked by two-storey oratories. Columns and pointed arches of red sandstone carry the net vault; a small roof turret marks the crossing.

The church was built between 1895 and 1897 under a Mainz Cathedral architect and continued to receive interior work until 1921. This construction period coincided with a time of economic growth for the town of Bad Kreuznach.

The parish is the seat of all parishes in the surrounding area, including St. Franziskus, St. Nikolaus, St. Peter and St. Wolfgang, and since January 2011 it also leads the parish community of Norheim (Kreuzerhöhung), Bad Münster (Maria Himmelfahrt) and Hüffelsheim (Hl. Schutzengel). Inside, the neo-Gothic furnishings follow designs by the architect Ludwig Becker, and the church keeps a silver-gilt sunburst monstrance made between 1724 and 1740 by the Cologne goldsmith Andreas Schmidt.

The church is open on weekdays during parish office hours and holds regular religious services for the community. Visitors should plan for standard opening times of an active parish church and be respectful of ongoing religious activities.

The smallest of the four bells cast in 1925 by the Otto foundry in Bremen-Hemelingen, the "Caritas" bell, survived both the wartime requisitions and the bombing that badly damaged the church. Four cast-steel bells from the Bochumer Verein were added in 1954 alongside it.
