Ottonian Architecture refers to the architectural style that emerged in the Holy Roman Empire during the reign of the Ottonian dynasty from the 10th to the early 11th centuries. This style is characterized by its grand basilicas, extensive use of brick, and the incorporation of Roman elements, such as rounded arches and large towers. Notable examples include the Cathedral of Magdeburg and the Aachen Cathedral. The Ottonian period marked a revival of monumental architecture, influenced by earlier Carolingian designs. Buildings often featured intricate decorative elements, such as frescoes and sculptures, reflecting the era's emphasis on religious themes and imperial power. This architectural style laid the groundwork for the later development of Romanesque architecture.
