The university has approximately 15,000 students. History The town's Royal charter was granted in 1621 by King Gustavus Adolphus of Sweden. The original town was situated where Gammelstad (Old Town) is situated today. The town had to be moved in 1649 to the current site, due to the post-glacial rebound that had made the bay too shallow for ships to enter. The Gammelstad Church Town is a UNESCO World Heritage Site. In 1805, Luleå only had 947 inhabitants, but in 1865 Luleå succeeded Piteå as the county town in Norrbotten county and now had around 1400 residents. In the 1860s the industries also started taking root in the city. The town has been plagued by fires in 1653, 1657 and in 1887, and the fire in 1887 was a devastating fire that destroyed most of the town, sparing only a few buildings. The Neo-Gothic Cathedral (originally the Oscar Fredrik church), dedicated in 1893, standing at 67 meters (220 ft), is the tallest building in town.
