Recently some of the authors proposed a search for galactic axions with mass about 0.2~$mu$eV using a large volume resonant cavity, tens of cubic meters, cooled down to 4~K and immersed in a magnetic field of about 0.6~T generated inside the superconducting magnet of the KLOE experiment located at the National Laboratory of Frascati of INFN. This experiment, called KLASH (KLoe magnet for Axion SearcH), has a potential sensitivity on the axion-to-photon coupling, $g_{agammagamma}$, of about $6times10^{-17}$ $mbox{GeV}^{-1}$, reaching the region predicted by KSVZcite{KSVZ} and DFSZcite{DFSZ} models of QCD axions. We report here the status of the project.
