The parish church of St. Stephen was erected in place of an older church which was, in its turn, erected most probably on the foundations of an antique basilica. The legend says that margrave Engelbert of Istria and his wife countess Matilda were buried in the older church. The present-day church of St. Stephen was built between 1580 and 1614, obtaining its current shape at the end of the 18th century. Owing to the mannerist elements of its façade, it has been considered that it was built following the designs of the famous Venetian architect Andrea Palladio.
