The inscription on that window pane? A rather common catholic rhyme on little rural folk churches dedicated to the madonna:

I call to the weary hiker,
look at your your mother here.
Come in and put yourself
and yours under her protection.

Oh, I do not mean a pane you would open and close every day somebody is going inside.... Such would be a firm protective wood filling installed for the winter season to protect a glas window or in case of a former obsolete bell hole or smal airing opening in the nave sometimes it is there instead of a glas. Usually such panes are more lavishly painted like wedding trunks with religious imagery and rustic flower designs, but this looks very simple, not even a background colour and just a rhyme in pretty neogothic lettering, and from the inside I did not recall it. There are two simple little glass windows far below the porch roof you can see in the previous pic along with the side windows, and every bit free of space got votive art. If I remenber it right, the really big votive painting for the end of WWI hangs inside above the portal, such would explain a permanently shut off upper window of an almost modernist design, some provisoric filling that became associated with the buildings looks and kept.
