The Angelo Mariani Theatre is one of the oldest and most perfectly preserved wooden theatres in Italy. Located in the heart of Sant'Agata Feltria, this architectural gem is renowned for its exceptional acoustics. The village itself is a historical treasure, dominated by the imposing Rocca Fregoso, a fortress designed by Francesco di Giorgio Martini. Visitors can explore winding medieval streets, discover aristocratic palaces like Palazzo Fregoso, and visit the Convent of the Poor Clares. A major annual event is the 'National Fair of the Precious White Truffle,' which attracts gourmands every October. Nearby attractions include the spiritual town of Pennabilli, the unique landscape of the Sasso Simone and Simoncello Regional Park, and the ancient Republic of San Marino, offering a rich itinerary of culture, history, and nature.
