On the 3rd of May 1530 Emperor Karl the 5th, returning from his coronation by the Pope in Bologna me this brother, Ferdinand the 1st, Prince of Tyrol, King of Hungary and Bohemia and later Holy Roman Emperor at the so called "Plattlfelsen" on the southern edge of the village of Gries.

As a commemoration, the then chancellor of Tyrol, Bernhard von Cles erected a bronze relief at the meeting point with a Latin inscription describing the brother's greeting. These days a marble plaque commemorates this historic event. The area around the memorial became locally known as "zum Kaiserbild" or "the Emperor's plaque."
