The Chapel of the Holy Trinity was built from an unusual material in 1915-1917. It belongs to the style of the man-made caves and built with the slag, which was a by-product from the former Rothauer ironworks.
The pastor of lead town Georg Marck and the plasterer Joseph Fischer took part in the construction work. Unfortunately, Joseph Fischer was taken to the front, but even under these circumstances he worked on the completion of the chapel. But he did not see the finished work because he fell near Tarnopol on September 28, 1915.
