After having been for centuries the heart of the Empire, from the 3rd century the government and the cultural center began to move eastward: first the Edict of Caracalla in 212 AD extended Roman citizenship to all free men within the imperial boundaries, then during Constantine's reign (306–337) the seat of the Empire was moved to Constantinople in 330 AD.
The Italy Pavilion features a plaza surrounded by a collection of buildings evocative of Venetian, Florentine, and Roman architecture. Venetian architecture is represented by a re-creation of St Mark's Campanile (bell tower) and a replica of the Doge's Palace. The pavilion's design is inspired by other hallmarks of Italian architecture, such as the Neptune Fountain (reminiscent of Rome'sTrevi Fountain) and the Il Bel Cristallo shop (meant to resemble the exterior of the Sistine Chapel). Musicians, clowns, and acting troupes often appear in the piazza throughout the day. There are also small shops selling Italian goods, such as candy and wine.
