Ameglia's Baffling, Trapezoidal Fortress: A Puzzle of Antiquity

Castello di Ameglia, formerly known as castrum de Ameliae, nestles in the picturesque town of Ameglia, residing in the Province of La Spezia. For six centuries, it acted as a command post for local governance, until they flitted off to the present-day municipal palace in the urban district. What sets this castle apart from others? A peculiar, not run-of-the-mill, trapezoidal fortress wall, you say? Indeed, that's just the tip of the iceberg. Despite numerous attempts to trace its genesis, it remains a cipher, yet it's generally conceded that it was erected during the time of the bishops of Luni. Today, the castle continues to be a beacon in Ameglia, spurring strolls through its grounds, allowing the mind to wander back to the Middle Ages as a defender of the castle.
