Billund () is a town in Jutland, Denmark. It is the home of the Lego Group head office. It is also the site of a theme park, Legoland, waterpark resort, Lalandia, and Billund Airport which is the second largest airport in Denmark. The airport opened in 1964 and was built by the Lego Group, but is now run independently. With a population of 6,742 (August 2022), Billund is the second largest town in Billund Municipality, behind the municipal seat of Grindsted. On the outskirts of the town there is a Lego factory, which, , manufactured 90% of the company's products. Adjacent to the company's headquarters is the first Legoland theme park, which opened in 1968 and is called Legoland Billund. In addition to the Lego Group, Sun-Air of Scandinavia has its head office in Billund. History Billund has long been part of the parish of Grene Kirke ("Grove Church") whose original Romanesque building was first mentioned in 1291. The town's name was first mentioned as "Byllundt" in 1454 and as "Billund" in 1510. In 1880, the town's first windmill was built on the road between Vejle and Varde. In 1895, the mill burned to the ground but was rebuilt in 1897, this time in the style of Dutch windmills. That same year, a railway was built from Vejle to Billund, and the route was later extended to Grindsted in 1914. In 1916, Ole Kirk Christiansen, who later founded The Lego Group, bought Billund Machine Joinery and Carpentry Business from master carpenter Steffen Pedersen, who had originally founded it in 1895. The business constructed houses during the summer and produced furniture in the winter. He invested in the town, creating a new dairy and the Skjoldbjerg church a few miles south of town. In 1924, after his house and workshop burned down, Kirk Christiansen built a house at Hovedgaden in Billund with two stone lions placed at the entrance. Due to the impact of the Great Depression, people in the town were unable to afford to build houses, so in 1932, he began producing utility items such as ironing boards, stepladders and miniature toys. The toys became the main product of the business and in 1934, he named the toy factory "Lego". In the late 1930s Billund experienced growth due to the factories and began to build waterworks, a gymnasium, and the town hall, though the local power station was closed
