GRAPES-3 the old site which is called GRAPES-3. The GRAPES-3 experiment at present is operating with ~400 (each 1 m) plastic scintillator detectors with a separation of 8 meters, to record the density and arrival time of particles in cosmic ray showers, and in continuous operation. At present, GRAPES-3 array is the highest density conventional EAS array in the world, and also, this experiment associated with a huge 560 m area tracking muon detector, is also the largest area tracking detector anywhere. Several results have recently been obtained from the GRAPES-3 experiment on a variety of topics, a few of which
