Over the years, numerous artists have stayed in this village and made it their custom to leave a sign of their passage. Casoli has gradually turned into the village of graffiti: the best way to admire it is with a walk through the quiet alleys, observing some of these artist's traces and some of the views of the surrounding landscape. One comes across works that immortalise scenes of everyday life or local characters, or even myths such as the graffito taken from the Odyssey and the one depicting Narcissus as he is reflected in the water. The latter is located not far from the historic centre, in the lower part of the village, inside an old washhouse.
The walls of the entire village are decorated in shades of red, yellow and brown, with which graffiti, known as sgraffiti, is mainly made. The process that leads to their creation requires precision and meticulousness: sandstone, coloured lime and metal powder are used, in a technique that balances art and craftsmanship.
