Ground plan of the Circus of Caracalla in today Capena outside the Porta S. Sebastian, in the two boards meet together 

Giovanni Battista Piranesi’s “Ground plan of the Circus of Caracalla in today Capena outside the Porta S. Sebastian, in the two boards meet together,” is a detailed architectural drawing of an ancient Roman Circus. The plan is presented in an orthogonal perspective, highlighting the dimensions and layout of the arena and surrounding structures. Piranesi was known for his meticulous depictions of Roman ruins, and this work showcases his mastery of architectural drawing, with emphasis on the grand scale of ancient Roman architecture. This drawing is a valuable resource for understanding the functionality and design of the Circus of Caracalla, a monumental structure that hosted chariot races and public spectacles.
