Carolingian Architecture refers to the architectural style that emerged during the reign of the Carolingian Empire, particularly under the rule of Charlemagne in the late 8th and early 9th centuries. This style is characterized by the revival of Roman architectural elements, such as the use of arches, vaults, and columns, combined with new innovations like the westwork and large towers. Key examples of Carolingian Architecture include the Palatine Chapel in Aachen, which showcases a blend of Roman and Byzantine influences. The style laid the groundwork for later medieval architecture, influencing the development of Romanesque and Gothic styles in Europe.
