am not sure to have seen them in Germany or other European countries. They commemorates the victory over the plague. Here in Baden is called the Trinity Column, and it is written there that was built in 1714. It seems that the plague badly affected Vienna and surrondings in middle
1600's. I am wrtting the palgue but I should write
a plague, because Vienna appears affected several times, over the years, by plagues. The plague and the rats are closely related, do not forget it.
