The Basilica of Santa Maria Assunta in Aquileia is a masterpiece of inestimable historical value, known primarily for housing the largest early Christian mosaic in the Western world. Dating back to the 4th century AD, this extraordinary floor work covers over 750 square meters and narrates, through colored tesserae, biblical scenes such as the cycle of Jonah and complex symbolisms like the struggle between the rooster and the turtle. Beyond the mosaics, the Basilica is an architectural palimpsest where the Romanesque style blends with Gothic and Renaissance elements. Of great suggestion are the Crypt of the Frescoes, with 12th-century Byzantine paintings, and the Crypt of the Excavations, which allows walking over the remains of the ancient Theodorean structures. The majestic bell tower, which dominates the Friulian plain, was built in the 11th century using marble recovered from the Roman amphitheater, a symbol of the indissoluble link between the imperial city and its Christian heritage.
