Neo-Byzantine is an architectural style that emerged in the late 19th century, characterized by its revival of elements from the original Byzantine architecture. This style often features large domes, intricate mosaics, and ornate decorations, reflecting the grandeur of ancient Byzantine churches. The movement was particularly popular in the United States and Europe, where architects sought to create buildings that evoked the spiritual and historical significance of the Byzantine Empire. Notable examples include the Cathedral of St. John the Divine in New York City and the Basilica of St. Mary in Minneapolis, showcasing the style's distinctive features.
