There are lots of locked doors that require keys to open in "Assassin's Creed Valhalla." Some of these keys are very challenging to obtain, particularly the Londinium Bureau Key. To help players save a lot of time in the game, they could use some tips and tricks on this guide to find the key.
Where to Find Londinium Bureau Key Location in "Assassin's Creed Valhalla"
To locate the Bureau in "Assassin's Creed Valhalla," players need to go to the northeastern part of Lunden. They would notice several ruined Roman architecture and a circular wooden fence structure. From there, they could climb the wooden fence and dive into the pool that they could see below.
Instead of climbing out, players have to dive down under the pool's surface and use Odin's Sight. Still underwater, they would find a treasure and to their left is a wooden barrier that can be broken. "Assassin's Creed Valhalla" players need to smash through this and swim down until they can surface.
To the players' right, they would notice that one of those breakable walls that could only be destroyed by using explosive red pots. Before that, players have to grab a nickel ingot by diving underwater again under the suspended wooden platform around the corner. It is in the small gap that contains a chest.
After that, players should climb up onto the wooden platform and jump across the building, the one with grated windows. From there, players need to pull themselves up and move to the window in the center. Players would see some red jars put on the other side of the breakable wall. "Assassin's Creed Valhalla" players must use their bow to shoot them and break down that barrier.
Players have to use ropes and poles to climb up to the open window, and once inside, they would have access to all the goodies in that place. This includes the Magas Codes page, the "Assassin's Creed Valhalla" Londinium Bureau Key, and the Hidden One's Mask. Players can use the key to open the door that offers players a quick way to go back to the pool where they first dived into.
Other Details
Players would discover that in the note, the Londinium Assassins went to Cologne, Germany. While this does not confirm a German Assassin's Creed game, but it reveals that there is a presence of an Assassin in the region. Now that players have the Londinium Bureau key location, they could get back to their Viking activities.
From there, players just need to find the movable block opposite the wall with the three banners and move it to go back outside. To leave the place, players need to follow the steps at the end of the pool, move the barrier sideways, access the crack, and go out through the wall.
