Judging by the relative uniformity of construction, the castle of Chlemoutsi appears to have been built within a few years, c. 1220–23. Most of the architectural elements found in the castle are typical of French 12th-century architecture; as K. Andrews writes, "lacking purely Gothic features, it appears to be more a transition from the Romanesque". A few native Byzantine elements are also apparent, as in the impost blocks or in the use of local material.
