Lego unveils giant replica of St. Wenceslas Crown at Prague Castle

Lego has unveiled a 280-kilogram replica of the St. Wenceslas Crown on Hradčany Square in front of Prague Castle, celebrating 25 years of its Kladno factory. The model, built from 128,333 bricks, is larger and heavier than the historic crown, offering visitors a unique opportunity to view the iconic symbol in an unusual form.

The exhibition highlights Czech cultural heritage while combining creativity and education, appealing to both children and adults. Through Sunday, visitors can explore Czech history and art at Hradčany Square, making the display accessible to those new to the country or seeking family-friendly cultural experiences.

The Lego crown took approximately 490 hours to build, with around 200 Lego Model Production employees contributing to the project. Michaela T. Horáková, general director of the Kladno factory, said the project “combines Danish creativity with Czech precision and attention to detail,” emphasizing the collaboration between production and marketing teams.

To ensure stability and safe transport, the Lego bricks are glued together and supported with metal elements.

The model includes the crown only, while the traditional scepter and orb were not part of the exhibit. Colored bricks were carefully selected to simulate gemstones, with multiple tests conducted to match the original crown’s appearance.

The exhibition, open through Sept. 21, features an interactive educational zone where visitors can build their own mini crowns or miniature king figures. The activity is designed to encourage learning through play and to foster creativity while teaching historical context.

Diplomatic and institutional support underscores the event’s significance. Danish Ambassador Søren Kelstrup and Czech Ambassador Jiří Ellinger attended the unveiling, and the project received backing from the Czech Confederation of Industry.

The Kladno Lego factory, established in 2000, is the second-oldest Lego production facility worldwide. It spans over 124,000 square meters—roughly the size of three Wenceslas Squares—and produces models for international markets, Legoland parks, and retail stores.

The crown project highlights the factory’s ongoing role in global Lego production and showcases Czech craftsmanship on an international platform.

Visitors can view the crown in Prague before it moves to the Central Kladno shopping center for the holiday season. The company has not yet announced a permanent location for the replica.
