I invite you to take a short walk through night Vienna.
Cathedral of St. Charles Borromeo. Its construction was completed in 1737. This is an unusual cathedral, it combines elements of different styles and eras: an ancient Greek portico, ancient Roman columns, like Trajan's, two baroque pavilions and a large dome that resembles the dome of St. Peter's Cathedral.
Just a view of the street of Vienna from the hotel window.
Albertina Gallery. In 1996-2003 Albertina was closed to the public due to reconstruction. A year after the resumption of its work, the Albertina became the most visited museum in Austria. Currently, there are no graphics in the permanent exhibition of the museum, they are shown only during temporary exhibitions. The museum's collection includes graphics by such artists as Leonardo da Vinci, Michelangelo, Raphael, Peter Paul Rubens, Oskar Kokoschka, Rembrandt, Albrecht Dürer, Gustav Klimt, Egon Schiele, Cezanne and Rauschenberg. The museum hosts specialized exhibitions of painting.
Of course, you can't do without an illuminated fountain. It looks great. A special effect is achieved by changing colors. I'm sure there is a fountain like this in your city too, they are very popular now. But although they are very common, they are no less beautiful.
That's it, the short walk is over :)
