Archaeology integrated into the Hellenic Cadastre, ending property market grey areas

With the new partnership between the Ministry of Culture and the Hellenic Cadastre, the Archaeological Cadastre is entering its next phase of development by integrating its data with the geospatial framework of the National Cadastre.

Although the Archaeological Cadastre has been operational for several years, archaeological information remains fragmented. Designated protection zones, archaeological sites, historic places, and the restrictions imposed under archaeological legislation are not always fully aligned with the cadastral data used by the property market. As a result, engineers, investors, and notaries are often required to consult multiple public authorities to verify the legal status of a property.

According to official figures, cadastral data have been published for 99% of the country, with National Cadastre Identification Codes (KAEK) assigned to registered properties. The existence of this unified geospatial framework now enables cultural heritage information to be linked with property ownership records on a nationwide scale.

The initiative is built around three key pillars. The first is the full integration of the Archaeological Cadastre with the National Cadastre’s geospatial infrastructure, allowing archaeological sites, monuments, and historic places to be mapped within a common reference system. The second focuses on the comprehensive registration of the Ministry of Culture’s real estate assets, with the aim of strengthening protection against encroachments and improving asset management. The third pillar involves the geospatial mapping of Protection Zones A and B, archaeological sites, and the surrounding areas of monuments.

This mapping will provide a clearer picture of each property’s location in relation to protected areas and the restrictions arising from archaeological legislation, while also streamlining administrative procedures such as property transfers and the issuance of building permits.

To implement the partnership, joint technical working groups will be established to harmonize datasets, define common technical standards, and expand interoperability between the two systems. At the same time, new digital services and public information initiatives will be developed to make the Archaeological Cadastre more user-friendly and accessible, in conjunction with the Hellenic Cadastre’s Digital Cadastral Mapping Platform.
