We present Version 1.0 of the World Atlas of Last Interglacial Shorelines (WALIS), a global database containing samples and sea-level proxies dated to Marine Isotope Stage 5 (~70 to 130 ka). The database was built through manuscripts and associated datasets compiled in a Special Issue of the journal Earth System Science data ( We collated the single contributions (archived in Zenodo at this link: into an open-access standalone database. Database documentation is available at this link: Version 1.0 of the database contains 4005 sea-level index points and 4390 dated samples connected with several tables containing relevant metadata (e.g., elevation measurement techniques, sea-level datums, and literature references).
