The simplest design in Greek order is the Doric order. This order was developed in western and mainland Greece and is considered the most primitive and basic of the orders. The Doric order is known for its short columns, which are well-organized, heavy, and feature round, plain capitals without a base. Here are some key features of the Doric order:

No base underneath the column
The capital (top) of the column is plain and round
Frieze has triglyphs and metopes alternating with each other
Entablature is simple and plain, with no decoration or ornamentation
Overall, the Doric order is a simple and straightforward design that has been used in many ancient Greek buildings. Its no-frills style has influenced many other architectural styles throughout history and continues to be appreciated for its timeless simplicity.
