Billund is a small town in central Jutland, Denmark, with a population of around 6,000. It is almost entirely defined by two things: Legoland (the original, opened 1968) and Billund Airport, which is Denmark's second-busiest airport and serves most of Jutland. The Lego Group has its global headquarters here and the town exists largely to service the park and its visitors.
Legoland Billund was the world's first Legoland when it opened in June 1968. The park features Miniland — a scale model of cities and landmarks built from millions of Lego bricks — alongside rides, shows, and themed areas for children up to around 12 years old. The adjacent Lalandia resort (opened 2009) adds an indoor water park, bowling, and family accommodation. Together they make Billund a viable two- or three-day family destination.
The Lego House, opened in 2017 and designed by Bjarke Ingels Group, is a separate attraction in the town centre aimed at older children and design enthusiasts. It is worth a visit even if you skip Legoland.
Outside the parks, Billund is unremarkable — a corporate headquarters town in flat Jutland. The interest is in the surrounding region: Jelling (15km north) has Viking rune stones and a UNESCO World Heritage church that are among the most important monuments in Scandinavia; Vejle (30km east) is a more conventionally attractive town with good restaurants and a fjord setting; Givskud Zoo (20km west) is a large safari park. Koldinghus, a dramatic medieval castle in Kolding (50km east), is worth the drive if you have a car.
