Conference Site

The Zappeion Exhibition Hall, also known as the Athens Conference Hall, is a building located in the National Gardens of Athens, Greece. It was built in the late 19th century and was named after Evangelos Zappas, a wealthy Greek philanthropist who funded the restoration of the ancient Olympic Games. The Zappeion was built on the site of an earlier building, the garden house of the Duchess of Plaisance, which was demolished to make way for the new structure.

The Zappeion was designed by Danish architect Theophil Hansen and was completed in 1888 and it was the first building in Greece to be constructed entirely of steel, which was imported from Germany.

It was originally built to host the events of the first modern Olympic Games in 1896, including fencing, wrestling, and weightlifting. Since then, it has served various purposes, including as a venue for conferences, exhibitions, and other cultural events. In addition to hosting events during the first modern Olympic Games in 1896, the Zappeion was also used as the official press center for the Athens 2004 Olympic Games.

The Zappeion is considered to be one of the most important examples of neoclassical architecture in Athens. Its façade features a central portico with six Corinthian columns, and its interior is decorated with murals and sculptures depicting Greek history and mythology. The building has undergone several renovations and restorations over the years, including a major renovation in the 1980s to prepare it for hosting the European Union summit in 1983.

In addition, starting in 1936 and for the next 40 years, it hosted the country’s first state radio station. In 1940 it was converted into a hospital; the following year it was commandeered by the German occupation army after which it became a storehouse and later a barracks (1944). It was even bombed during the same year.

After the war, the possibility was discussed of demolishing it. Fortunately, in 1960, general repairs were carried out under the supervision of architects A. Ploumistos and F. Panagiotopoulos. The most recent renovation was carried out in connection with the Olympic Games of 2004 which were held in Athens.

The Zappeion Exhibition Hall has witnessed  the history of Athens for the past 120 years. It has been a key site for some of the nation’s most significant moments, and has always been integrally linked to the Olympic Movement. Even though its uses were varied, it has become a landmark in the Greek capital, thus fulfilling the donor’s initial wishes. The Zappeion has been used for a wide variety of events over the years, including art exhibitions, fashion shows, concerts, and even a performance by the Rolling Stones in 1967.

Today, the Zappeion remains a popular venue for conferences and events, as well as a popular tourist attraction in Athens. It is located in the heart of the city and is surrounded by the National Gardens, making it a peaceful and scenic retreat in the bustling urban center.
