As in many cities, the view of the roofs in Venice is outstanding. But Venice wouldn’t be Venice without a peculiarity even on the top of the buildings! If you look attentively you will see the most of the chimneys have an uncommon form. They look like inverted barrels or truncated cones. This particular form comes from the beginning of the Serenissima Republic when the Venetians had to adapt to the conditions of the place. Humidity, saltiness, dwellings very close to each other and of different heights make the expulsion of fumes from the chimney difficult and particularly dangerous for fires. Building the chimneys like inverted cones allows hindering and cool the sparks.
