Dr. Franz von Wirer
The first person to use the salt baths in the area for medicinal purposes was Dr. Josef Götz. When he told Dr. Franz von Wirer about his work, the good doctor made the town famous by turning some of his famous patients onto this new miracle in medicine. You see, von Wirer was a professor at the Vienna Medical School and was the personal doctor for Emperor Franz I.
Bad Ischl was visited by the Austrian Kaiser every summer for a longer vacation...
...the Kaiser enjoyed the simple life here in the mountains, and rich people and who-ever could afford it , also spent his summer-vacation here, and the small village became an important town.
This small river is also called "Ischl"
And like the Kaiser, rich people wanted to have their "summer-palaces" or at least summer-houses, and plenty of these houses can still be seen.
Also Franz Lehar, famous Austrian Composer of Operettas had a villa here.
and this looks like a palais - but it is simply the local post office.
But of course Bad Ischl needed an extra-large postoffice because of the Kaiser's summer residence.
And today it is really a bit oversized, and as far as I know, it should be sold.
Bad Ischl, or as most local people would say "Ischl" is still an importand spa with salt&sole-cure and has plenty of big hotels.
This is the congress-center of Bad Ischl
