ANTARES is the first undersea neutrino telescope and, at present, the largest one in the Northern hemisphere. Its main goal is the search for high-energy astrophysical neutrinos. It consists of an array of photomultipliers tubes housed in so-called optical modules, detecting the Cherenkov light induced along the path of relativistic charged particles originated by neutrino interactions in and around the instrumented volume. ANTARES, has been acquiring data in its final configuration since 2008. The excellent optical properties of the sea water and the location of the telescope allow for the reconstruction of neutrino event direction with very good angular resolution, and for high sensitivity searching for possible sources in the region of the Galactic plane. The most recent results of ANTARES searches for neutrino point sources, for diffuse neutrino emission from several interesting regions, and for neutrinos from WIMP annihilation in massive objects like the Sun and the Galactic Center will be presented. Particular attention will be given to the multimessenger approach, presenting the wide program of combined searches in collaboration with astronomical observatories, with cosmic ray experiments and, recently, with the LIGO/VIRGO interferometers.
