Lillestrøm's history dates back to the times river powered sawmills came into use for the production of building materials.

However, the almost non-existent property values were judged to be a fair exchange and so the workers started living and settling in the area around the sawmill, and Lillestrøm was born.

The event is commemorated in an annual 4-day street fair, which includes music by high-profile Norwegian artists on several outdoor stages, food stalls, retail business exhibitions, and thrill rides.

The whole thing (with free admission to all) is held in Lillestrøm's main thoroughfare and its connecting streets, which are closed to all vehicles for the duration.

However, this is overshadowed by the much larger international airport at Gardermoen (opened 1998), which is 25 km (16 mi) further north but just 12 minutes away from Lillestrøm railway station by high-speed rail.

[10] Facilities in Lillestrøm include hotels, Norway trade fairs, a brand new cinema, a mall, Lillestrøm torv, restaurants, a high speed commuter train that reaches both Oslo and Gardermoen airport (the Gardermoen Line), a community cultural house (kulturhus), and a community outdoor swimming pool complex.

During the 70s, the club went through the divisions with back-to-back promotions before eventually winning the double in 1977, largely thanks to their legendary player Tom Lund.

There are also two indoor arenas, one multi-purpose (Skedsmohallen) and one for football (LSK-Hallen), and in 2007 a track and field stadium Romerike Friidrettsstadion was built as a cooperation between the municipalities Skedsmo, Rælingen and Lørenskog.
