A post-chaise is a travelling carriage operated in the 18th and early 19th centuries, travelling from staging post-to-post, and changing horses at each stage. With an enclosed body on four wheels, seating two people, and drawn by two or four horses, it is basically a chariot carriage with the coachman's seat removed. Riders, called postilions, rode the near-side (left) horse of each pair pulling the carriage.
