It was great to see so many teenagers at the museum. This museum is about the Indonesian youth independence movement. We could hear violin versions of Indonesia Raya (the Indonesian national anthem) everywhere, and we took the opportunity to see the actual violin of W.R. Soepratman, the man behind the anthem.
The ticket price is very cheap, only Rp 2,000, to bring out your nationalist spirit. There are many comics from the first and second congresses of the Indonesian Youth Movement that you can read while listening to the national anthem. Bring a guide with you to learn more about the movement.
