Hjälmaren is Sweden's fourth largest lake. It lies West of Stockholm and is connected to the city by a channel. The lake is 63 kilometres long, up to 20 km wide and has an average depth of 6 m (with a maximum of 22 m) and an area of 483 km2. On the Western bank of the lake lies the city of Örebro. The lake has become an iconic spot in Sweden by the music festivals that are organized on the banks. Among others ‘The Smashing Pumpkins’, ‘Sonic Youth’ and ‘Pearl Jam’ performed here.
Like many places in Sweden, Hjälmaren is also known as a product of Ikea, in this case storage racks. On the internet I find this description: the Hjälmaren storage series is all about simple ways to get what you want, from towels to your hairbrush. There is even a cart with boxes to organize for your bits and pieces and to move them to where you need them!
