Dreifaltigkeitskirche (Holy Trinity Church), Graz

The Holy Trinity Church is a Roman Catholic church, located just off Schlossbergerplatz in the fifth Grazer district. A monastery, formerly Ursuline, and a school of the Sister Klara Fietz Volksschule, is adjunct to the church on the northwest side.

The church was built in 1704 by Bartholomaus Ebner and intended for the Ursulines. Construction of the connecting monastery lasted from 1700 to 1722. The monastery was designed by Anton Leithner. The church stands today on the site of the former city moat. Now the church is managed by the Franciscan sisters order.

The church was built in the Italian Baroque style but it has altered a bit to the Habsburg Baroque. It could be called South German-Austrian Baroque. The facade has monumental columns, a cornice and a semi-circular voluted gable. The Archangel Michael in full battle armor is ensconced above the portal, triaging the Last Judgement.

Observing the judgement from flanking side niches, are Mary and Joseph. The pediment is ruled by the Holy Trinity, Father, Son (Jesus), and Holy Spirit in the shape of a stucco dove. A thin roof turret on the side of the Mur river closes off the gable.

The interior is baroque throughout. The nave is vaulted. There are side chapels and galleries. The high altar reasserts the dedication to the Holy Trinity. Sculptures of the Fathers of the Church, Gregory the Great, Hieronymus, Ambrosius and Augustine, appear between heavy columns. God the Father and Saint Ursula also appear.
