In February 2022, after 16 years of continuous operation, the first deep-sea neutrino telescope, ANTARES, was powered down for the last time. During the week of October 16, 2023, meeting of the ANTARES and KM3NeT collaborations, we will also organize a day dedicated to the celebration of the end of the ANTARES project whose scientific inauguration was also celebrated at Paris Diderot University in 2008. For this occasion, we are waiting for all the collaborators of the project for 25 years but also national and international scientific personalities, and senior representatives of research funding organizations. The event will have a likely media echo, as it will be associated with a public exhibition at the CNAM.
