The Fasti Online Project of the International Association of Classical Archaeology celebrated its 20th anniversary in 2023. The project website is composed of three portals for accessing excavation, heritage conservation and archaeological survey datasets. The database of archaeological excavations and interventions currently contains more than 6,000 georeferenced and illustrated records, mainly from Italy, Greece and Eastern Europe, each in the national language and in English. The database of field survey projects currently contains more than 500 records mainly from Mediterranean countries, and has been developed since 2016 in collaboration with the Royal Dutch Institute in Rome (KNIR). In 2024, the website will be redesigned with a new platform based on Omeka, an open-source content management system for online digital collections. The information collected in the project is open to the public and its contents are currently being used by other important projects, funded both by international organisations, such as ARIADNE+. 

This presentation shows the research tools offered by Fasti Online, indicates future lines of development and collaboration with other projects, and proposes the integration of new tools for improved geospatial analysis of its digital contents.

At the same time, some examples will be presented to illustrate the diachronic analysis of lived spaces in sites with a large amount of information, such as Pompeii or the city of Athens, observing the evolution of both public and private structures using different search criteria available in the advanced search section (Monument Types; Site Location and Site Date Range).
