The Oral History Team of the Employees of EYDAP was created as part of the collaboration among EYDAP, the Cultural Center, its employees and retirees, and the Historian Tasoula Vervenioti, with the primary purpose of collecting oral testimonies in connection with the construction of the Marathon Dam. The aim of this action is to narrate the stories and preserve the memory of the people of EYDAP by collecting those narratives that will eventually constitute a solid basis for the creation of an oral record of the long history of EYDAP, an asset which will in its turn be put into the service culture and education. This is a pioneering venture undertaken by a Greek company with the purpose of preserving and spreading the local shared cultural heritage. The collection of oral testimonies enriches the already existing Historical Archive of the Company, which is of great importance and constitutes a valuable part of the national cultural capital, by accumulating written and oral sources related to the history of modern Athens.
