Ilulissat, formerly Jakobshavn or Jacobshaven, is the municipal seat and largest town of the Avannaata municipality in western Greenland, located approximately 350 km north of the Arctic Circle. With the population of 4,541 as of 2013, it is the third-largest city in Greenland, after Nuuk and Sisimiut. The city is home to almost as many sled-dogs as people. In direct translation, Ilulissat is the Kalaallisut word for "Icebergs". The nearby Ilulissat Icefjord is a UNESCO World Heritage Site.
