Introduction to the Cave Gallery: In front of the Naplashti Bridge connecting the fourth and fifth atriums, there is a fashionable gallery built using underground caves. The maze-like cave displays exhibitions from the Czech Republic, Poland, Hungary, Romania, the United Kingdom, Modern art works from European countries such as Germany and Russia, as well as from countries around the world such as the United States and India. The dark and silent cave seems to be a completely different world from the noisy and noisy streets.
