What is this place? And how to open the door? (Batman: Arkham Origins)

It seems that this is the Crypt of Cyrus Pinky. To open the door, you need to scan the pages from his diary. They are scattered around the city.

This is a quest. you need to find the diary pages or something of one architect of Gotham. Look, in steam in the manuals

What do they look like?

kirill643Like pages)) They are hidden behind engraved plates. On the bridge that connects the two parts of the map, look at the leg of one of the statues. Don't forget to turn on the detective mode.

I saw them, but "Detective" doesn't see them and I can't scan them. Don't know why?

Makhno Incorporated
So I have all the pages. Well, to be honest, I downloaded the save.

You need to scan the Anark signs, they are scattered throughout the city and there are 20 of them (visible only in detective mode)
