The “Carlo Siemoni” Forest Museum is dedicated to Karl Siemon, a Bohemian forest engineer invited to manage the Casentino forests for Grand Duke of Tuscany, Leopold II, in 1837. The museum houses photographs, giant prints of flowers and wildlife, a geological model of the land, natural environment reconstructions, a xyloteque, and taxidermy mammals native to the Apennines.

Adjacent to the museum lies the Arboretum, established in the mid-19th century by Siemon. Initially designed for experimentation and acclimatization of exotic forest species, the arboretum has grown to feature indigenous and centuries-old trees of numerous varieties. Since the 1950s, the Arboretum has expanded to include 139 species across three hectares, originating from various corners of the world.
