Everyone who visits this interesting city surely goes to the Republic Square. The locals like to call it the guest house of Yerevan. It's built of pink tuff(Armenian traditional stone) and has a huge carpet image made from stones right in the middle of the square. This place is always beautiful and interesting but especially in the evenings it gets more crowdy and lively because of the evening program called 'singing and dancing fountains.' They play very loud music of different styles starting from classical to jazz and traditional Armenian music.There are bright and cloroful lights that start from the fountains and change with the rithm; the water streams also change their shapes with the music. The whole show is very entertaining and fun plus it is really beautiful. If you go to Yerevan in summer time check this show out.
