The baroque Karlskirche (St. Charles's Church) in Vienna was build between 1713 en 1736 to commemorate the end of a large plague epidemic.
The height of the dome is 70 meter, and the two flanking columns are based on Trajan's Column in Rome.
The golden triangle high above the altar shows the tetragrammaton, or YHWH (Yahweh), the name of God in the Hebrew bible. It means something like 'I am' or 'To be' or 'He who creates'.
