The Swiss School of Archaeology in Greece (ESAG) (French: École Suisse d'Archéologie en Grèce; German: Schweizer Archäologische Schule in Griechenland; Italian: Scuola Elvetica d'Archeologia in Grecia; Greek: Ελβετική Αρχαιολογική Σχολή στην Ελλάδα) is one of the foreign archaeological institutes operating in Greece.
Since 1964, the Swiss archaeologists have been excavating the remains of the ancient site of Eretria (Euboea), a medium-sized city which has extensively contributed to the development and the influence of the Greek civilisation.
Hosted in Switzerland by the University of Lausanne, the Swiss School has its head office in Athens, in an Art Nouveau building at Odos Skaramanga 4B.
In 1975, after the end of the rule of the military junta (1967–1974), the Swiss Mission requested and received the title, habitual in Greece, of "School of Archaeology".
The third phase (1996–2009) is marked by a new spurt of excavation activity with the exploration of a sector located not far from the House of the Mosaics, which led to the discovery of the Industrial Quarter as well as remains going back to the second millennium BC.
Thanks to the excavations it has conducted and the research it has organized -from the study of the data gathered in the field to their publication- the Swiss School of Archaeology in Greece provides a valuable framework for cultural exchange: many professors, doctoral candidates, advanced students, and interns from Swiss universities have in fact taken part in the activities of the School and in the study of Eretria's past.
All the projects are subject to the authorization of the Greek government's Ministry of Culture, and the provision of advance notice to the Ephorate of Euboean Antiquities, which is also responsible for overseeing the activities.
In 1974‒75, a team from the Swiss Federal Institute of Technology Zurich drew up a map showing numerous 19th-century houses and proposed that they be preserved.
The creation of an archaeological zone in the region between the Temple of Apollo Daphnephoros and the House of the Mosaics, which constituted an important part of the 1975 project, has sporadically inspired interest.
In terms of specific accomplishments, the School has restored a 19th-century house that belonged to Admiral Nikodimos, one of the heroes of the Greek War of Independence, and also established its headquarters in Eretria.
