Why visit this specific department store in Moscow? GUM distinguishes itself because of its historical significance. It was established more than a century ago and used to be the Soviet Union’s State Department Store. Nowadays it’s like any other mall, but swankier and prettier on the inside and out. It has several shops, cafes, restaurants and movie houses for those who want to go shopping, eat and watch movies. Its interior is Instagram-worthy, if you don’t want to buy anything, you can just take pictures.
