I arrived in Trieste during Pope Francis' visit to the city. Sightseeing was much more difficult due to the crowds of believers and the large screens placed in churches and main city squares. Taking advantage of the sunny morning, I admired the picturesque boulevards and neoclassical architecture of the Borgo Teresiano district. In the afternoon, I went to Grotta Gigante, the world's largest karst cave, located on a plateau above the city.
