Karlskirche is dedicated to Saint Charles Borromeo and the two columns at the Church's entrance have relief scenes of his life and are modeled after Trajan's Column in Rome.
Also on the columns are several gilded eagles... representing the Habsburg monarchs.
Karlskirche, also known as St. Charles' Church was completed in 1737.
This website (

"The most striking feature from the front of the church are the two columns that stand either side of the portico. These are modeled on Trajan's Column in Rome and depict scenes from the life of Charles Borromeo. The left hand column illustrates the qualities of Steadfastness, while Courage is shown on the other. The columns also lend an imperial theme to the church, convenient as the commissioning emperor, Karl, shared the same name as the saint. The columns are topped lanterns with an imperial crown on each and surrounded by Habsburg eagles."
