Poland 🇵🇱—Warsaw Palace of Culture and Science

The Palace of Culture and Science is the tallest building in Warsaw. You can go to the top floor to enjoy the whole view of Warsaw. For safety reasons, the surrounding area is sealed with iron mesh, and you can see some people locking couple padlocks on the iron mesh. In addition to climbing to the top, the Warsaw Palace of Culture and Science holds events regularly. The day I went was the last day of the book fair, so there were a lot of people.
