A peristyle is an architectural feature that consists of a row of columns surrounding a courtyard or garden. This design is commonly found in ancient Roman and Greek buildings, providing both structural support and aesthetic appeal. The open space created by the columns allows for natural light and ventilation, making it a pleasant area for relaxation or gatherings. In classical architecture, peristyles often serve as a transition between indoor and outdoor spaces. They can be seen in famous structures like the Pantheon in Rome and the Temple of Apollo in Delphi. The use of peristyles reflects the importance of nature and open spaces in ancient architectural design.
