Karlsplatz situated just southern from Ringstrasse is one of the biggest squares in Vienna and probably my focal point for all kinds of traffic. There is huge U-Bahn station where 3 lines meet (U1, U2, U4) stretching all the way to Staatsoper and Kaertner strasse. Karlplats is quite interesting. It hosts one of the most beautiful churches in Vienna, Karlskirche. There is fountain in front of church. But before all Karlsplatz is park with many green areas and trees and there are playgrounds for children as well as basketball playgrounds, there.
Very impressive looking art nouveau architecture. I especially like the stenciled floral drawing on the wall.
Designed by Otto Wagern (one of the Secession movement artist) it was supposed to be the urban train stations....but were there trains then!!!
This is Karl Church, the big church at the Karlsplatz where you have a small park and war memorial for the red army soldiers.
Henry Moore's Hill Arches are a sculpture sitting in Karlsplatz by the reflecting pool in front of Karlskirche. They were presented to the city of Vienna in 1978.
The photo shows the old Wagner Pavilion at Karlsplatz. Otto Wagner was an Art Nouveau architect. He constructed the underground rail in some sections around 1900.
