In the Four Confessions District, at 16 Pawła Włodkowica Street, a new mural has been created. Its main subject is Aaron, the first Old Testament high priest of ancient Israel. Interestingly, the mural looks completely different during the day than it does after dusk. When it gets dark, it shines and a figure - invisible during the day - appears on it.

The mural was painted as part of the activities planned on the occasion of the completion of the reconstruction of Michael Engler's organs, which after 46 years returned to the Basilica of St. Elizabeth.
