The church of the Jesuits, who settled in the town in 1626, was built between 1634 and 1641, modelled on the Roman church of Il Gesu. By 1667 the convent and the school were completed.
The interior of the church is in early Baroque style. The high altarpiece depicting the glorification of St Ignatius and the ceiling paintings of the sanctuary and nave (the Assumption of the Soul of St Ignatius and the Angelic Greeting) was painted by Paul Troger, a prominent Viennese Baroque artist, and two of his companions. The beautiful Baroque pulpit was built in 1749 and the organ cabinet in 1755. Above the organ is a fresco of an angel concert. The richly carved pews and doors are decorated with a shell pattern. There are three chapels on either side of the nave. Their decoration is older than that of the nave.
In the Chapel of the Way of the Cross, which opens from the sanctuary, there are relief statues of Mária Pátzay, made in 1980. After the dissolution of the Jesuit order in 1802, the Benedictines began to use the complex.
