The chapel contains "two most exquisite and remarkable figures executed by the Austrian sculptor, (1818-80) of Munich, and representing in painted wood the Blessed Virgin weeping over her divine Son, who has just been taken down from the Cross, the nails being laid at His feet". A student of Konrad Eberhard, Petz was also an architect and an artist and was highly sought after in England and the United States as a sculptor and church designer. Several locations for which he designed churches and their decorations are Cham, Arnschwang, Seeon, Vilsbiburg, Isen, and Riedering. Most notably, he contributed the design for a sculpture of the Last Supper for the Frauenkirche in Munich in 1859, though this was lost in air raids during World War II.
