The Swiss School of Archaeology in Greece (ESAG] (; ; ; ) 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. The school has also offices in a 19th-century neoclassical house in Eretria, Odos Apostoli 15.
