The town is situated close to Stockholm's main international airport, Arlanda. Even if its origins go back to around 500 AD, Märsta is a widespread modern residential area. Märsta has a mix of multi-storey dwellings and smaller houses. It is in a phase of expansion and new residential areas are built both in central parts of Märsta and in the surrounding areas like for instance Steningehöjden.
