Are you looking for the Gotham Knights landmarks? To confirm that you have seen one of the many landmarks in this open world game, you need to read its corresponding plaque. Luckily, all of them are at ground level, and you just need to interact with them to register their entry in the database.
Of course, there are other collectibles outside of the 40 Gotham Knights landmarks. The Gotham Knights Batarangs are perhaps more annoying than the landmarks to track down as they can be anywhere. There are also 12 Gotham Knights street art murals to find, and they're a lot easier. But with that in mind, here are all of the Gotham Knights landmarks.
