Rocca Ubaldinesca, Renaissance fortress in Sassocorvaro Auditore, Italy.
Rocca Ubaldinesca is a brick fortress in the Marche region featuring a distinctive turtle-shaped layout with an internal courtyard rising prominently above the Foglia River valley. The structure was designed to function as both a defensive stronghold and a commanding presence over the surrounding landscape.
Francesco di Giorgio Martini designed this defensive work in 1475 for Ottaviano degli Ubaldini, an advisor to Duke Federigo da Montefeltro. The construction was part of a broader series of fortifications erected throughout the ducal territory.
The fortress served as a crucial refuge for art and continues to function as a place where Renaissance works connect with visitors from different backgrounds. Its dual identity as both military structure and cultural repository shapes how people experience and understand the space.
The site is best reached on foot with the climb from the town being clearly visible and requiring some effort. Visitors should wear sturdy shoes and allow time to explore, as crowds are generally small and the environment is quiet.
During World War II the fortress sheltered more than 10,000 artworks from different Italian cities, protecting them from wartime destruction. This role as a storage vault earned it the nickname 'Ark of Art'.
