One of many Vienna buildings in the style called Jugendstil here
Desert View Watchtower, Grand Canyon National Park, Arizona
A visit to the Desert View Watchtower on the eastern portion of the Grand Canyon’s South Rim. Constructed in the 1930s, it offers magnificent canyon views and a tie to the Native American history of the Canyon.
I believe it’s the ‘Majolikahaus’ near the Naschmarkt, which was designed by Otto Wagner. I have educated myself and now know that the term refers to a type of tile. If you look closely you can discern the individual tiles.
Thanks! You got ahead of me on the research. And in Vienna, so much! Everywhere I turn, I find more wonderful examples, and that’s before I even start a systematic look!
