Andrea Palladio died 6 months after construction began on the Teatro Olimpico in 1580. His pupil Vincenzo Scamozzi completed it — including the most famous theatrical illusion in architecture: 7 stage openings with streets built in forced perspective, tilting upward and narrowing so dramatically that streets 12m long appear to stretch 100m into an ancient city. The illusion is so convincing that audiences still gasp 440 years later. The Teatro Olimpico is the oldest enclosed theatre in the world still in use — and a UNESCO World Heritage Site that most tourists skip because Vicenza isn't on the standard Italy trail.

The auditorium (cavea): Semi-elliptical seating for 400, modeled on Roman theatres (Palladio studied Vitruvius obsessively). Statues of the Accademia Olimpica members line the top — the intellectual club that commissioned the theatre. The scaenae frons (stage wall): A two-story Classical facade with columns, arches, niches, and statues — modeled on a Roman triumphal arch. The perspective streets: 7 openings in the stage wall, each containing a street built in forced perspective. Stand at the center of the front row: the central street appears to extend 100m into Thebes (the set depicts the Greek city of Thebes for the inaugural play, Oedipus Rex, performed February 3, 1585). The set has never been changed in 440 years.
