More than 700 extraordinary sites, many of them inaccessible or little known, will exceptionally open their doors for the 15th edition of the Autumn Days organised by the Italian Environment Fund (FAI). The initiative, set for Saturday, October 10th and Sunday, October 11th, allows the public to learn about Italy's rich historical, artistic, and environmental heritage. As always, the selection of openings will be diverse and unexpected, ranging from monumental structures to theaters, from churches to educational institutions, from natural areas to castles, and including art collections, examples of contemporary architecture, and unusual and curious sites. In this edition, the FAI will focus on Italian craftsmanship and Made in Italy, highlighting—through special openings and visits—the knowledge, ancient crafts, manufacturing traditions, and manufacturing excellence that, along with historical, artistic, and landscape assets, contribute to defining the identity of the regions and making Italy a global reference point.
