Why were the Tivoli Gardens important to the Danes of Copenhagen in Number the Stars by Lois Lowry?

The Tivoli Gardens were a place of enjoyment for the citizens of Copenhagen before the Nazi occupation. The Danes enjoyed the fun they had there. In Number the Stars, Annemarie recalls her happy memories of the Tivoli Gardens. One day, Ellen and Annemarie play Gone With the Wind with their paper dolls, and they decide the setting should be the Tivoli Gardens. During this playtime, Annemarie remembers what the gardens had been like.

Annemarie recalls "music and the brightly colored lights, the carousel and ice cream and especially the magnificent fireworks in the evenings" (Chapter 4). She was quite young when her parents used to take her to the Tivoli Gardens. By the time the novel begins, the Tivoli Gardens are already closed. When the Nazis occupied Copenhagen, they burned down part of the Tivoli Gardens. Annemarie does not know what their exact intentions are, but she assumes the Nazis set fire to the Tivoli Gardens as "a way of punishing the fun-loving Danes for their lighthearted pleasures."
