Dipylon is a non-profit organization for the study of ancient topography and the cultural environment through interdisciplinary research on Archaeology, History, Informatics, and Cartography. We are interested in the collection, organization and dissemination of published archaeological material, archival documents, and cartographic data to promote cultural assets using digital technology. Dipylon’s general interests lie in the multiple layers of habitation of a place, the diachronic evolution and the transformations of urban space. Currently, our efforts focus on the study of the topography of ancient Athens and Attica.
