Norman architecture, also known as Romanesque architecture, is a style of architecture that emerged during the 11th and 12th centuries. This style is characterized by its rounded arches, thick walls, and sturdy columns. This architectural style can also be referred to as Norman Romanesque, Romanesque Revival, Norman Style, or simply Romanesque. However, it is important to note that while these terms are often used interchangeably, there are subtle differences between them. For example, the term "Romanesque Revival" is used to describe the 19th-century revival of the Romanesque style, while "Norman Romanesque" specifically refers to the style of architecture that emerged in Normandy.
