Underwater cultural heritage

Switzerland ratified the UNESCO Convention on the Protection of the Underwater Cultural Heritage on 25 January 2020. The aim of the convention is the protection and long-term preservation of the world's underwater cultural heritage. The world's seas and inland waters harbour numerous testimonies to the human past that are of great cultural value – ranging from submerged landscapes, settlements and shrines to ancient docks and shipwrecks.
