About the Archives

The Historical Archives of the European Union (HAEU), located in Florence, Italy, is a research centre dedicated to the archival preservation and study of European integration.


The HAEU is the official archives for the historical documents of the Institutions of the European Union, and is home to more than 150 private archival deposits from eminent European politicians, movements and associations, as well as a collection of documents relating to European integration from National Archives and Ministries of Foreign Affairs Archives. These holdings document an important part of the post-World War II efforts in European integration and cooperation.


The HAEU was established following decisions by the European Coal and Steel Community and the European Council in 1983 to open their historical archives to the public. A subsequent agreement in 1984 between the European Commission and the European University Institute (EUI) laid the groundwork for establishing the Archives in Florence, and the HAEU opened its doors to researchers and the public in 1986.


Since then, a 2011 Framework Partnership Agreement between the EUI and the European Commission reinforced the Historical Archives’ role in preserving and providing access to the archival holdings of the EU Institutions. In 2012, the HAEU moved into the historic Villa Salviati. It is a state-of-the-art archives facility, with 11,000 linear meters of shelving available, offering magnificent views of the Tuscan countryside from Fiesole to Florence.
