When we were in Puglia in September, I noticed that high baroque churches and palazzi were placed in narrow streets, making it impossible to get a proper view of them. The grand duomo in Gallipoli was a case in point, so were the houses in Martina Franca.
Now, reading Wölfflin’s Principles of Art History, I found that in his view this was not a mistake and was wholly characteristic of the baroque style. His concept of the “painterly style” in baroque denoted movement, indefiniteness and impermanence in the visual arts and applied to sculpture and buildings as well as painting.
The creation of views in architecture, in which buildings were designed to be seen in different ways and from different perspectives, was one aspect of the painterly style and explains why it was unimportant for a façade to be viewed square on or from the front:
Although the full front view will always claim for itself a certain exclusivity, we now find compositions which clearly set out to reduce the significance of this view. This is very clear, for instance, in the Carlo Borromeo church in Vienna [the Karlskirche, above], with its two columns placed in front of the façade, the true value of which is revealed in the non-frontal views, where the columns lose their equality and the central dome is cut across.
For the same reason it was regarded as no misfortune if a baroque façade was so placed in a street that it was almost impossible to obtain a front view of it.
