St. Francis Xavier Cathedral, Roman Catholic cathedral in Banská Bystrica, Slovakia.

St. Francis Xavier Cathedral is a brick structure with two towers crowned by onion-shaped domes that rise above Slovak National Uprising Square. The main entrance is framed by four Tuscan columns that give the building classical proportions.

A Gothic chapel on this site is first recorded in the Königsberger testament of 1503; it remained the town's only Roman Catholic place of worship during the 16th century, when Banská Bystrica was held by Protestants. Jesuits settled here in 1647, built their college on the site in 1695–1701 and began the church in 1702 as a copy of the Gesù in Rome. Work stopped in 1703 under the anti-Habsburg troops of Francis II Rákóczi, resumed in 1709 and the church was consecrated on 24 September 1715. The Jesuits left in July 1773 when Pope Clement XIV suppressed the order, and since 1776 the church has been the seat of the diocese.

Locals usually call it Kapitulský kostol, the Chapter Church, because it has served the diocese since 1776. The Jesuits who built it were expelled in July 1773 when Pope Clement XIV suppressed the order, and the church passed to the diocese. The name honours St. Francis Xavier, the Jesuit missionary.

The cathedral is easily identified from the street and regular worship services take place at Namestie SNP 27. Visitors should remember that this is an active place of worship where respectful behavior is expected.

The church was built from 1702 as a copy of the Church of the Gesù in Rome, but the towers were not part of that design: the façade stood without a tower until 1844, when two onion-shaped towers were added during a large rebuilding. The Jesuits who began it were expelled in July 1773 when Pope Clement XIV suppressed the order.
