According to Mariska Beirne of Zurich Tourism, the Rosenhof-Passage makes it possible to stroll through the Old Town without actually having to walk and without getting wet in rainy weather. The murals are however not only a guide for visitors. They are above all a homage to Zurich and to the great Swiss artist Rudolf Koller, animal and landscape painter, who spent his childhood in the Hotel Adler. One painting that made Rudolf Koller famous is the "Gotthardpost," created in 1873 and depicting a mail coach descending the Gotthard Pass at great speed. It is said that, in his childhood, the painter chalked his impressions on the walls and wardrobes of his parent's establishment. The present owner of the Hotel Adler, Peter Krause, is a big Koller enthusiast, and it is he who commissioned the Rosenhof murals.
