Chiemsee sundials

Dear Friends
yesterday I have had the occasion to visit with the colleagues of my Directorate the Herren Insel on the Chiemsee here in Bavaria:

and let me say that I was delight in discovery on the fassade of the old Augustiner Abbey two very interesting sun dials. Later on at Prien, on the bord of the Chiemsee I have seen another, modern sundial. I send you the images of the sundials. Any comment from your side is welcomed.
Salutations
