Thanks to blog reader Christian Baumann, a completely new version of my Cryptologic Travel Guide is now avaible. Almost 100 museums, libraries, graves and other sights with a relationship to cryptology are now displayed on an interactive world map.

There are hundreds of places in the world that are worth seeing for people interested in cryptology. This is why I have created a list of cryptographic sights. I hope, my readers can help me to extend it.
