Form - Karlskirche
Prandtauer (a religious brother) emphasized verticality through fluted pilasters and a dome on pendentives that soar high. St. Charles's Church contains a dome in the form of an elongated ellipsoid. The façade in the center, which leads to the porch, corresponds to a Greek temple portico. The neighboring two columns, crafted by Lorenzo Mattielli, found a model in Trajan's Column in Rome. Next to those, two tower pavilions extend out and show the influence of the Roman baroque (Bernini and Borromini). Above the entrance, a dome rises up above a high drum, which the younger J. E. Fischer shortened and partly altered.
