The Zappeion Megaron, conceived by the architects Theophil and Christian Hansen, is a distinguished exhibition and conference hall situated in the heart of Athens. Its neoclassical design is beautifully executed with the extensive use of Pentelic marble, which lends the building its luminous and imposing presence. The Zappeion’s grand marble columns, sweeping staircases, and detailed friezes epitomize the elegance of ancient Greek architecture. As a central venue for cultural, political, and social events, the Zappeion Megaron’s marble construction not only enhances its visual appeal but also reflects the enduring legacy of classical aesthetics in modern Greece.
