There are 19 Foreign Archaeological Institutions in Greece. Seventeen of them are officially accredited Foreign Institutes (also known as "Schools"), all based in Athens. Most of them contain specialised archaeological/Classical libraries, run regular lecture programmes, award scholarships/bursaries and offer accommodation.
Some of the institutes also maintain permanent dig houses or study centres outside Athens.
Additionally there is one separate foreign-run Archaeological library in Athens, as well as one foreign research institution elsewhere in Greece.
