The Chapel of St. Anthony of Padua remained of the medieval church, while further architectural interventions began from the 16th century onwards. It still remains identical to the form received in the first half of the 18th century. The old Žminj castle wall was used for its lateral façade. The front façade of the church was completed in 1717 due to immense dedication of parish priest Sante Rovis. The church contains typical features of Istrian Baroque of provincial character with Renaissance elements, similar to the Baroque stile found in northern Italy. In the middle stands the statue of St. Michael, the patron saint, dating back to 1727, which dominates the entire façade. In the niche on the right is a statue of St. Rocco and on the left St. Sebastian. Priest Mihovil Rovis financially provided the embellishment of the façade with the previously mentioned statues. There is also a stone rosette made by Ivan Marinac, Žminj’s priest and canon. This church’s façade is unique in Istria because of its distinctive tympanum. The main altar was also commissioned by Žminj’s canon and priest Sante Rovis in 1706. Its slender columns are made of local stone coming from a quarry in Gradišće. From 1994 there is a new marble altar in use, along with a pulpit (an elevated platform for reading the Holy Bible excerpts). Two years later the church floor received new tiles. Behind the church tabernacle there is a painting of St. Michael (oil on canvas), work of academic painter Eugene Kokot from 1997.
Baroque pulpit
It was built in the first half of the 18th century from multi-coloured granular stone from a quarry in nearby Gradišće. This artistically valuable work of a foreign artist from central Europe is considered to be one of the greatest works of the 18th century Baroque in Istria. In 1745 Bishop Gaspare Negri from Poreč visited the church and declared it stands out for its high aesthetic value.
Adoration of the Shepherds
This piece of art was made as a carving by a local master in 1690 under the influence of stylizations of the High Renaissance. It is protected as cultural property of the Republic of Croatia. Located in a niche inside the chapel of St. Anthony of Padua, it is considered to be the most valuable monument in the church. Its distinctively baroque style features distinguish the portrayal of the evangelists and of St. Michael on the fence of this majestically composed marble pulpit, unique in Istria.
