Beyond the many hidden weapons and armor pieces of Dying Light: The Beast, there are also some Treasure Maps you can locate to go on a scavenger hunt, and one of the first is the Treasure Map E3. Since you don’t get any markers on the map or an exact location, all you can do is follow the clues and hope you find the place where this treasure is. Yet, if you’re still struggling to find it, here’s the solution to Treasure Map E3 in Dying Light: The Beast.
Treasure Map E3 Solution

You’ll get Treasure Map E3 once you access Old Town’s Town Hall during the main story of Dying Light: The Beast. Once you have it, it will be added to your collectibles menu so you can check it at any time you want.
Initially, the only clue you get is that there’s a heavily secured apartment not far from the city belfry. If you’re unsure what a belfry is, it is where the town’s bell is, and one of the largest buildings in the game’s starting area. You can use the image below as a reference.

The easiest way to reach the belfry is by climbing to the top of any building and parkouring to that spot. That way, you won’t lose sight of the belfry.

Once you arrive, look for one of the streets that has an orange apartment with an open window and white curtains. If you enter it and use your Survivor’s Instinct, you’ll notice several golden things that are glowing, as well as one Investigation item.

The Investigation note mentions several areas that have been checked, but it says that one is still unexplored: Trattoria. If you turn around from where you found the note, you’ll see the aforementioned building and an entrance to it.

Go inside, defeat the zombies, loot anything inside the building, and then interact with the body.

After moving the body, you’ll find a key, which you can then use in the locked closet in the apartment where you found the note.

Return to the apartment, use the key to complete the treasure hunt, and grab all the loot. It is full of valuables and one healing item. Or at least that was in our case. In any case, that’s a wrap on Treasure Map E3, which will likely be the first scavenger hunt for many players.
