The question kind of feels like a conspiracy theory ready to be unraveled but it’s a serious question that a lot of people do not know the answer to. LEGO® lasts for a long time, it’s close to near indestructibly (especially feels this way when you tread on one) but does LEGO® really keep a copy of every LEGO® set in a secret underground vault? Let’s not waste any further time and jump straight into the detail.

Key Takeaway

Who created The First LEGO® set?

The first LEGO® set was created by Ole Kirk Christiansen and his son Godtfred. Ole Kirk Christiansen and his son Godtfred created the first LEGO® set in 1932. This LEGO® set consisted of 8 or 10 wooden toy bricks.

With the LEGO® set being made out of wood each brick had to be sanded down by hand to make it smooth before it could be sold. Can you imagine if LEGO® was still made of wood now, I mean wow that would be interesting to see.

As far as we are aware there are no wooden LEGO® sets stored in their secret vault, however cool this would be I am not sure the concept of keeping a copy was thought about back in 1932!

LEGO Keeps a Copy of Every Set They Have Ever Made

Why would LEGO® want a copy of every set they have ever made?

LEGO is not alone in having its own secret vault to store its products, for example, Disney has one, and it’s quite common within the music industry as well.

Before I go on any further as far as I am aware at the time of writing this the oldest set they have stored in their secret underground LEGO® vault is from 1966 so it’s not quite every single set they have made which is fairly understandable.

LEGO has always been popular but going back 50+ years the production and distribution of the sets were not quite as efficient as it these days. Technology and additional services have moved on quite rapidly to allow LEGO® to scale and achieve the mammoth business it is today.

Going back to the question, one of the reasons LEGO® would want to keep a copy of every set they had made could well come down to legal reasons. They, of course, hold copyright against their sets but once a set is retired if there was a legal battle that required a LEGO® set as evidence the only sets out there would be in a used condition or owned by collectors. Whereas in this scenario LEGO® can take their copy (I believe they keep a few not just one of each) and that can be used as required throughout the legal case.

I am not sure there has actually been a scenario where this has happened but it’s definitely one of the drivers to keep a copy.

The next reason we will cover in the next section is to create a tourist attraction!

Can You Visit The LEGO® secret vault?

This is an interesting question and surprisingly the answer is yes although it’s not called a vault, the official term is LEGO® Memory Lane.

LEGO have actually made their secret underground vault part of their tour for those serious collectors out there who would get a buzz out of seeing the LEGO® hoard!

Hey, I am Matthew Mitchell and I am an AFOL from the UK. I have been fascinated by LEGO® since I was a child. My two children are in love with LEGO® and it's because of them that my interest continued to grow, this is how I fell in to the rabbit hole of MOCs (my own creation). 

With every new MOC I saw I became just a bit more addicted to the endless possibilities that LEGO® offers. This led me to creating Belle-Ve Bricks, a platform where talented designers can share their work with the world.

And where we can create together with you, custom models.
