Treasures of Monteriggioni
If you're having trouble finding a treasure chest in Monteriggioni, chances are that it's in this video.
Six of the treasure locations are inaccessible until you pay the architect for certain renovations. They are covered in the video as follows:
The Well - 2:21
The Mines - 4:01
Military Barracks - 5:18
The Brothel - 6:20
The Church - 7:39
Thieves Guild - 8:30
Most of the others are easy once you buy the in-game map from the Art Merchant in Monteriggioni. Some players have difficulty finding the two chests in Ezio's third story room of the Villa. That one is covered at 1:41.
Ok, at the moment I have 14/30, all from story missions though as I try to have minimum health. Il get started on this after my uni assignment is finsihed
Should've ended the video at step 3.

Whoever you are holding me now in hand,
Without one thing all will be useless,
I give you fair warning before you attempt me further,
I am not what you suppos
Thanks for the shoutout in the link, nice vid
I was going to do something very similar but I have to start a new game to do so
My video was going to just show the renovation videos. I would have the menu open where the architect is, and I would renovate a site and skip to that area. You did something pretty much the same but also got other treasures.
So before I make my next video, are you planning anything on codex pages? I was going to do the DLC but i would have to rent the game out again
Are you planning anything on codex pages?
No, I don't have plans for a video on Codex pages. The most frequently asked question has been, "I'm missing Codex page number x. Where is it?" It would be good if your video showed the map location and page number prior to collecting each one.
