Pre-Romanesque art and architecture
The pre-Romanesque period in European art spans the years from the emergence of the Merovingian kingdom around 500 AD (or from the Carolingian Renaissance in the late-8th century) to the beginning of the Romanesque period in the 11th century. While the term is typically used in English to refer primarily to architecture and monumental sculpture, this article will briefly cover all the arts of the period.
