On August 8 last year i was in Mainz in the church with the Marc Chagall stained glass windows https://en.m.wikipedia.org/wiki/Marc_Chagall

Yesterday I cycled back to Ein Kerem to see his windows in the synagogue in the Hadassah (huge hospital and medical research complex). https://www.hadassah.org.il/en/chagall_the_inspiration/
