Miloš Křeček (Czechia) has been a LEGO® enthusiast ever since he received his first set for Christmas at the age of five.

Today, he owns the world’s largest collection of LEGO® sets with 6,005 sets when last verified on 21 June 2023.

After decades of diligent collecting of thousands of rare and valuable sets, it became clear that home display cases would not be enough for all the exhibits.

That’s when Miloš realized that he wanted to display his possessions proudly for the whole world to see.

“The quantity of the accumulated sets and the lack of space led me to an idea for the opening of the first [LEGO®] museum in Prague,” he explained.

The Museum of Bricks, with branches in Prague, Kutná Hora, Poděbrady and Špindlerův Mlýn, holds most of Miloš’s ever-growing collection.

The avid collector is often asked how much time he has spent building the sets in his lifetime, but he cannot give a precise answer.

“Unfortunately, this cannot be calculated in any way,” he says. “But on average, one set will take you about two hours and my collection contains over 10,000 models, so we get to 20,000 hours, which is over two years put together.”

His all-time favourite set is the Statue of Liberty with a factory designation 3450, which he received on a New York sightseeing boat around Liberty Island, where the real Statue of Liberty is located.

“I bought more than 90% of all LEGO® sets myself,” he clarified, “but sometimes I will receive a set for my collection from my customers or acquaintances, which makes me very happy.”

He and his wife even gave rare LEGO® pieces as wedding presents to each other!

According to Miloš, the most difficult LEGO® for him to assemble was the LEGO® Star Wars™ 75313 AT-AT™ model.

“It was quite a challenge to assemble, with a total of 6,785 pieces. [But] the set that took me the longest to assemble was the new LEGO® Icons set 10307 The Eiffel Tower, with 10,001 pieces, which is also the tallest building of its kind with a height of 150 cm.”

What many people wonder about, is the monetary value of such a vast collection.

“There are a lot of [expensive sets],” Miloš shared. “For example, LEGO® Cloud City from Star Wars with a current selling price of over 250,000 CZK (£8,608.50; $10,944.07).

“I currently have a crush on the minifigure of  Mr. Gold. […] The price of this minifigure increases by approximately 30% every year. The current purchase price is over CZK 85,000 (£2,928.70; $ 3,723.27).

“[When talking about the value of my collection], we are talking about amounts in the tens of millions of CZK and more… The value of the collection is incalculable.”

Miloš may hold the record for the world’s largest collection of LEGO® sets, but he isn’t anywhere near done collecting his beloved sets, as there are still a few that he hasn’t been able to find or acquire.

“For example, H.C. Andersen's Clumsy Hans. A total of 400 pieces of this quite special kit were produced for two separate events.

“320 of them were distributed to holders of lifetime passes to Legoland Florida and the rest just to the participants of LIT 2015. […] The model is based on a LEGO statue by Dagna Holm. The current estimated price is over CZK 120,000 (£4,136.50; $5,257.77).”

As the collection keeps growing, more Museum of Bricks branches will be opening in other cities of the Czech Republic, proving that “breathtaking works of art can be created from a children's kit.”

Currently, the Museums store a total of over 6,751 different original sets, which grow by another 300 models every year – deriving either from Miloš’s private collection or by other contributors.

These are not only new models, but also old models and various collectible rarities.

The Museum of Bricks also places great emphasis on developing the creativity and playfulness of visitors. This is why it includes a play corner and a generously equipped shop, where one can find everything from commonly available LEGO® building blocks to limited editions and rare sets that are not sold anywhere else.
