The Porta Malatestiana, located at the beginning of the very central Via Giovanni Pascoli, dates back to the first half of the 15th century, a period in which several works were carried out. The gate was connected to the fortress by a dense system of corridors and tunnels. In 1518 Count Ramberto Malatesta began the conversion of the existing complex by donating it to the Augustinian nuns. Recent restorations have maintained the entrance vault and the reinforcement of the walls
