The EAS Cherenkov light array Tunka-133 with ~3 km2 geometric area operates since 2009. Five winter seasons of data acquisition (~107 triggers) permitted us to reconstruct primary energy spectrum and mass composition in the energy range 6•1015 to 1018 eV. To start gamma-astronomy experiments in Tunka Valley researchers from a number of Russian and European Institutes arranged a Collaboration TAIGA (Tunka Advanced Instrument for cosmic ray and Gamma-Astronomy). The complex installation will consists of the net of wide-angle (1 sr. field of view) Cherenkov light optical stations (Tunka-HiSCORE ), several (~ 5) IACT telescopes based on spherical mirrors of 10 m2 area (Tunka-IACT) and muon scintillation detectors of the total area ~2000 m2.
