Located in the bustling Piazza del Nettuno, Palazzo Re Enzo is a cornerstone of Bologna's medieval heritage. Built between 1244 and 1246, the palace famously served as the residence-turned-prison for King Enzo of Sardinia for over two decades. Today, visitors are drawn to its impressive Gothic facade and the 'Whisper Wall'—an acoustic marvel under the palace's vaults where whispers carry across diagonal corners. While the interior is often reserved for high-profile events, it occasionally opens to the public, offering a glimpse into the city's storied past through its grand halls and historic courtyard.
