Wow! First off, the man working on 28 November could not have been more helpful. He got me set up with their free wifi-based audit guide, walked me over to the museum, and gave me a brief intro. Many thanks!
This place is really only about three rooms, but I spent two hours here. There is so much information and history packed into all the different orders and their corresponding insignia. The audioguide is amazing, but almost overwhelming with all the history, people, and dates! I had to pause it a few times to make sure I was actually taking in the pieces themselves.
Can't recommend this small but fantastic museum highly enough, and - pro tip - it's open on Mondays, when most places that appeal to tourists are closed. Use your time wisely! :)
