And that’s for a reason. The church is full of the most astonishing 19th-century frescoes, vestments and liturgical decorations that make you gasp. Everywhere is something to see. Besides the ancient art, you can also visit the tomb of Béla III, king of Hungary and Croatia between 1172 and 1196 or attend a service. Keep an eye on the church’s calendar, because they invite foreign church choirs and ensembles regularly, who give concerts in the historic building. For many decades, they touch the visitors of Matthias Church through the power of church music. The mostly classical music repertoire of the performing ensembles includes both spirituals and contemporary church music pieces.
