The Church of St Francis Xavier testifies to the power of the Jesuit College founded in Leoben in 1613. This early-Baroque building from the 1660s, attributed to the architect Pietro Francesco Carlone, offers a pilastered and corniced façade, flanked by two towers. Inside, the simple pilasters enable the black and gold tones of the original furnishings (1670) to stand out and there are overabundant grotesques typical of Austrian Jesuit Baroque churches.
