The TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy) facilities aims at gamma-ray astronomy at energies from a few TeV to several PeV, as well as cosmic ray physics from 100 TeV to several EeV. Combination of the wide angle Cherenkov timing detector TAIGA-HiSCORE with the 4-m class Imaging Atmospheric Cherenkov Telescopes (TAIGA-IACT) of FoV of 10x10 degrees offers a cost effective-way to construct a 10 km^2 array with the expected integral sensitivity about 2,5 10^{-14}erg cm^{-2} sec^{-1} for detecting gamma rays with an energy of 100 TeV for the 300-hour observation of a local source. Reconstruction of a given EAS energy with an accuracy about 15%, incoming direction with an accuracy about 0,1 degree and its core position with an accuracy about 5 -6 m, based on the TAIGA-HiSCORE data allow one to increase a distance between the IACTs up to 600-1000 m. At present the TAIGA first stage has been constructed in Tunka valley, ~50 km West from the Lake Baikal. Now it consists of 60 TAIGA-HiSCORE Cherenkov stations distributed over an area of.0,6 km2 and the first IACT of the TAIGA-IACT array. Before the end of 2019; it will include 110–120 wide-angle Cherenkov detectors on an area of 1 km^2, three IACT. This complex will allows one to prove experimental potential and advantage of the joint operation of the timing and imaging Cherenkov arrays and to star the search for Galactic PeVatrons.
