4000006 Production Kladno Campus is an Architecture set released in 2012. It was released exclusively to workers at the Kladno campus.


In 1999, LEGO announced plans to open up a production factory in Kladno, the Czech Republic.The factory was officially opened in 2000 with a small staff of 80 employees. The factory was eventually opened, and currently serves the needs of mainland Europe along with the Kornmarken factory in Denmark and the Nyiregyhaza factory in Hungary. It was announced in June 2013 that the factory would be expanded, and the expansion was completed on April 16th, 2015, with a total of three production facilities and a manual warehouse, with a total area of 140,000 square feet. It is estimated that due to this expansion, the Kladno facility has increased in capacity by nearly 30% and has around 700 jobs.


  • The set was released to Kladno campus workers in June 2012, and has not been widely distributed, making it one of the most valuable sets in the world.
  • Despite not being a widely circulated set, this is the only Architecture set based on a Czech building.
