The Stadtpark of Vienna is the green lung of the city centre. It was inaugurated in 1862 as part of the redesign of the so called Glacis, the previously untilled area in front of the dismantled city walls of Vienna. The sight was planned in the English landscape style and architecturally enriched around 1900 when the Wienfluss, a river going trough the park, was finally regulated and the City Railway was build. You see the river on the second picture and the modern iteration of the City Railway, our Metro line number 4, on the third picture. It always amazes me how this piece of artificial nature is able to snatch you from the urban madness of a concrete jungle and calm you down almost immediately, may it be just for a couple of minutes. A green lung truly.
