AC Unity All Nostradamus Enigma guides

Nostradamus Enigmas are side missions in Assassin’s Creed Unity represented by the scroll icon on your in-game map. Each Enigma has a starting position and three (and rarely more) hidden symbols scattered within a 300-400 meter radius from the start of enigma.

Each hidden symbol has a corresponding riddle that you need to solve in order to find its location. Finding solutions to these riddles can be very hard and you would need to know a lot about the French Revolution and Paris’ history to solve them without help. I used Google and Wikipedia articles quite a few times to decipher some of these. Later in the game I figured out that discovering landmarks (they are marked on your in-game map) and actually visiting them to unlock in-game database entries will also help a great deal in solving riddles. Almost all riddles correspond to some landmark’s description in the in-game database.

The symbols can be found on the ground, on windows, on walls, on statues, or any other objects but they become visible only when you activate your Eagle Vision. They also play a characteristic sound when you are nearby so keep your headphones on when hunting for riddle solutions.

Enigma missions are a great deviation from your regular assassination activities and they helped me learn a great deal about the French Revolution and Paris landmarks and history. I would recommend all inquisitive types to attempt doing at least a few of these and for collectivists among you there is a great reward in the end, when you complete all Enigmas.

Whole point of doing Nostradamus Enigma mission and solving all their riddles is to collect Nostradamus Fragments. You get one for each Enigma you solve. After collecting 18 Fragments head towards a secret room in the basement of the Cafe Theatre, and open the cage where your main reward Thomas de Carneillon Master Assassin Outfit is locked. To open the cage you will have to solve three puzzles (one puzzle gets unlocked after you get 4 fragments, second is unlocked at 10 and third is unlocked when you have all 18). Each time you solve a puzzle you will remove one protective layer of the cage until you can unlock Thomas de Carneillon Master Assassin Outfit.

    great guide. just a note that some people are finding it impossible to complete the first clue of mercurius due to a strange bug that does not allow us to examine it. hopefully ubi fix it

    1. N

      I had the same issue at first, what solved it for me was that when you start the mission you read from some kind of diary in the armor room. Did you also check the symbol right above the diary?
      I hadn’t and that’s why I could not examine the painting on the second floor.

        You saved my life, bro… haha

  2. S

    Man tnx for this, I salute to you dude, it took dome time finding all these . So my question ids how do you solve the 3 riddles in the armor room?? 😛

    1. C

      That my friend is easy 🙂 look on the walls and you will see symbols all around there, next to each is a corresponding constellation, on the floor you will see some more symbol and on the pillars more constellations, match the symbols on the floor and the constellations on the pillar in front of it to the corresponding ones on the walls 🙂 easy

    2. C

      Second door, manipulate the 3 switches to make the planets align with the ones on the floor 🙂 I’ll have the 3rd door as soon as I get to it 🙂

    3. C

      The third is actually quite easy if not annoying though, just climb around the room timing it so you don’t get hit by the vents as the gas comes out

  3. X

    great guide! used it for all but the easiest one (the first one on the list in the game).


  4. C

    Very big thank you for this, really appreciate your hard work and time *doffs cap*

  5. E

    thank you so much for spending the time so I didnt Have too. Everything was spot on!

  6. M

    Great guide. Really useful and user friendly. Like the way you explain the clues and how you worked them out.

  7. This is a great guide…
    Thanks, bro. Got me out of a few jams…

  8. P

    Hey, this is a great and unique guide! I especially like it because you explain your thought process behind it to give some hints before saying the final answer. It helps people like me out who don’t want to know what the answer is but are stuck or out of ideas.

  9. A

    Hey guys, a lot of the landmarks on my map don’t reveal themselves. They just say landmark on the map, even though I’ve visited them. At the moment I can’t do the Nostradamus Enigmas because the landmarks don’t appear on my database. Has anyone else having this issue. Could this be yet another bug. Thought that patch 3 might have fixed it but… nope.

  10. A

    Some of the Nostradamus Enigma icons don’t show on the map for me. Do I need to progress further in the story or is it just a bug?

  11. M

    I can’t thank you enough for these! I had NO interest in trying to figure them out but wanted to clear them off my map (and get the armor, I guess).

    Thank you so much!

  12. B

    Thank you! Amazing work, impressive dedication in finding all the solutions. Great guide!

  13. S

    Thank you so much .. With ur help i managed to understand and solve the riddles .. Im really grateful

  14. H

    thanks so much for the guides appreciate it thanks again

  15. R

    Excellent Guide! Just love it. Many thanks.

  16. J

    I can not find the one in Sorbonne le quartier latin

  17. C

    the last 8 enigmas won’t show up on the map for me, so I can’t even start it, do I have to complete all the missions in the campaing for the last 8 icons to show up?

    1. G
      Gosu No0b

      You shouldn’t have to progress much in the story to do enigmas. I did all enigmas when I was around chapter 9. They might not show up on the map if you did not reveal that part of the map with a Viewpoint so try that first.

      1. D

        I cant seem to match up the pillars in the armour room I’ve been on it for 2 days anybody have a PIC of the pillar’s as they need to be would be so grateful thanks in advance

    2. J

      Goto progress tracker can start mission from there

  18. J

    Thanks for the effort Gosu. Very clear and also very informative comments.

  19. W

    Just want to say thanks man! I deciphered most riddles on my own, but when I was stumped, or I was tired of running around the map (so I confirmed here before going to a location) your info came in real handy. I really like that you explained your mental process as well, made it feel like it wasn’t just a “go here” faq, felt more rewarding.

    Thank you for putting together the best guide available on the Internet! I looked at many other guides for help, but yours was the most thorough and simple to follow. Congratulations on a great job done.

  21. N

    you are amazing thank you so much

  22. B

    did try the riddles too harsh for me and it reminded me a bit of myst, mostly due to the thinking part, but myst was more graphical

  23. E

    thank you friend! i really wanted to get that cloth and i finaly got it your solution was very helpful. at last opening those three gates underground was hard but finaly i opened them! the cloth is very beautiful it’s like Altair’s cloth with just one difference and that is its color. 🙂
    Thank you so much.

    If not for these Guides, I would not even look for these.
    Having to do them 1 at a time and run all over is not my definition of fun.
    So glad y’all have the proper OCD to find & document these.

  26. S

    This guide is amazing. Not only correct and accurate, the details of the research and what the clues meant was wonderful just to read. Great job OP

  27. E

    thnx for the help.this was helpful

  28. T

    Thnx a lot bro. It was a lot of help to me. Cool outfit in the end.
    Super Thnx to the man who helped out. Took a while but still did it.
    Even showed some mates this website.

  29. E

    finally i not understand. was Tomas De Carneillon, Altair?

  30. P

    Hey can anyone help me. I’m doing the virgo enigma and I found the last riddle (or where it’s supposed to be) but it’s not showing up and there’s just a stall there so I can’t get to where it’s supposed to be. Any help would be appreciated

    1. I
      It's not actually on that place on the map go a bit northwest and look for a tall, standalone tower. The symbol will be on the top

      It’s not actually on that place on the map go a bit northwest

  31. S

    Thanks, man. This really helped, I appreciate the time and effort put forth in making this to assist all of us.

  32. C

    Help!! It says I have 17 of 18 but I don’t see anymore scrolls and I’m pretty sure I’ve done them all. I’ve unlocked all view points. Don’t know what else to do.

    1. C

      Found it! Lol I turned off the filters in the map and finally found the scroll I was missing

  33. C

    I’ve done all 18 of these and it says I’ve only collected 16 pieces.

  34. R

    WOW!! Great, great guide. Guides are usually so boring to me and I hate having to use them as it feels like it takes away from just playing but I honestly had a great time using these when I needed to. Easy to use and my favorite part was how you included your thought process and how you found it. Made it feel like more of an adventure than just cheating lol.

  35. S

    i followed everything, i did all the riddles and it says i only have 10 out of 18, and when i go to the map it shows i have no more, am i missing something?

  36. Y

    Love the fact you tell us how you figured out each enigma. Great guide.

  37. C

    I loved using this guide, made it much easier to enjoy solving the puzzles if I got stuck, especially as it explained the solutions instead of just being a ‘go here, go there’ walkthrough

  38. D

    Great guide. I would not have been successful without this guide because of lack patience!

  39. N

    Hey man thanks so much.. my gratitude cannot be expressed into words. I wouldn’t have been able to do it all without you and your team’s guidance.. at first I felt guilty you know being a gamer and all we tend to solve our own problems been doing so before we could afford the internet.. but after you said somewhere that in order to solve this you need to know a bit about Paris.. all that guilt went outa the window.. I.e I’m from an island in the south Pacific. Neighbouring country to Australia and New Zealand.. called Fiji.. all in all thank you for all the hard work you’ve done and thanks also for Thomas de Carneillon’s Master Assassin Outfit.. couldn’t have done it without you.. cheers!! ?

  40. H

    Awesome guide! I haven’t found anything without it. But I am currently stucked at the final parkour puzzle where steam nock you away from the wall. My caracter refuse to jump to the next holding about halfway into the puzzle and, of course, the steam eventually nock me from the wall again, again and again. Annoying!

  41. A

    This guide is fantastic! I really liked how you explained the reasoning behind solving the riddles, instead of just giving the answer. Because of this I didn’t miss as much of the learning, that the riddles were meant to provide.

    I liked, that my last riddle took me to the tomb of De Molay. What better place to finish the riddles?

  42. C

    Great guide. Thank you!

    This game is a gem all these years later giving it a second chance.

  43. W

    Thank you so much for this guide. It help me a lot. Amazing job.
