As a student of human rights and humanitarian affairs, I really enjoyed visiting the International Red Cross and Red Crescent Museum, and would encourage anyone interested in such issues to visit the museum. Even if you don't know much about humanitarian affairs, you're bound to learn a lot by the end of your visit. The subject matter is a bit depressing, but I found the visit quite informative and thought-provoking even though it's not exactly an up-lifting experience.
I spent about 2 hours at the museum, but you could easily spend more time if you watch every single video. There was also a concert right outside the entrance the day I was there.
The museum is divided into eleven areas which I've summarized from the museum's guide:
1 - Preserving life by the written word: Founded by Henry Dunant, the Red Cross is concerned with preserving human life. Six panels with text from the Bible, Koran, Islam, etc. represent the need to preserve human life.
2 - Preserving life by acts of mercy: Background on Florence Nightingale and Nikolai Pirogov who tended to those wounded in the Crimean War. Background on Clara Barton who cared for those wounded in the Civil War.
3 - The Battle of Solferino (24 June 1859): A panoramic slide show/film that reconstructs the Battle of Solferino. After the show ends, the screen lifts up and takes you into Area 4, the Foundation of the Red Cross: Background on Henry Dunant and drafting of the First Geneva Convention.
5 - Towards universality (1864-1914) - Film to show the Red Cross' involvement in armed conflicts.
6 - The First World War and prisoners of war (1914-1918) - Files of over 2 million prisoners of war are housed in the museum. They are still referred to today.
7 - The First World War (1914-1918) - Video depicting Red Cross assistance during WWI.
8 - Between the wars (1919-1939) - Film showing the Red Cross' activities in providing social assistance and disaster relief during peacetime.
9 - The Second World War (1939-1945) - Film clips showing Red Cross assistance during WWII.
10 - From 1945 to the 1980s
11 - Today: Displays of the latest news from the field and more films and interviews.
There are computers in the main entrance near the Cafe Dunant which allow you to learn more about the Red Cross through their interactive program.
The museum is every day except Tuesday from 10:00 to 5:00 pm. Free for children under 12. To get there from Cornavin (the main train station), take the 8 or F bus to Appia or the V or Z to Ariana.
