After coming out of the cathedral, we chose to walk to the Pearl Tower. In about 20 minutes, the snow was getting heavier and heavier. After playing on the three-storey roof, we could see that there was a vast expanse of white outside. The picture was the snow scene outside. Inside, there is an exhibition of Iceland's geographical landscape, an artificial ice cave, a dome movie to see the Icelandic landscape and Aurora introduction. Four floors coffee restaurant. Tickets are a little expensive. There is a shuttle bus to the concert hall. It seems that there are not many domestic tourists. I feel it's worth going.
