The Basilica di Santa Maria Assunta is a patriarchal cathedral in Aquileia, Italy, world-renowned for containing the largest Early Christian floor mosaic in the Western world. Constructed in 1031 over the remains of an earlier 4th-century church, the site preserves significant archaeological evidence of the Constantinian era. The mosaic floor covers over 750 square meters, featuring intricate depictions of biblical scenes, mythological figures, and portraits of the donors. Visitors can walk on elevated glass walkways above the original floor to inspect the preserved 4th-century tile work. The structure integrates Romanesque and Gothic architectural elements, reflecting the site's multi-layered history as a Roman metropolis. The crypt contains 12th-century frescoes depicting the life of Saint Mark and the origins of the Aquileian Church. The campanile, built in the 11th century, stands 73 meters tall and dominates the local landscape. The complex acts as a primary historical document for the spread of Christianity in the Adriatic region.
