The upper section of a classical order is known as what?

The upper section of a classical order is known as the entablature, which is a horizontal structure that rests on the capitals of columns and supports the roof or attic above. The entablature is typically divided into three main horizontal subdivisions: the architrave, frieze, and cornice. Each of these components has its own function and decorative elements.

The architrave is the lower section that directly sits on the columns, the frieze is the middle section often decorated with reliefs or inscriptions, and the cornice is the uppermost projecting part that usually has decorative molding. Understanding the entablature as the overarching structure helps illustrate how these elements work together in classical architecture to create a cohesive and aesthetically appealing design. The term encapsulates the combination of all three parts rather than any single element, highlighting its importance in classical orders.
