Protestantism in Ustroń is as old as in the other towns of Cieszyn Silesia. It dates back to the first half of the sixteenth century. After its heyday at the turn of the sixteenth and seventeenth centuries, Protestants were subject to persecution, which only ended with the issue of the Patent of Toleration by Emperor Joseph II in 1781. It was then, when the first wooden house of worship was erected. The present church of the Apostle James the Elder was built in 1838. It is the largest church in the town located below Mount Czantoria.
