[1] During the 20th century Glostrup developed from a small railroad town into a modern middle class suburb.

While most of Copenhagens western suburbs are dominated by public housing projects, Glostrups mix is around the Danish average.

A series of large companies, e.g. Grontmij's and Motorola's Danish sections, along with NKT Holding and Pandora are situated in the area.

The village is first mentioned between 1186 and 1197 as Glostorp, but Glostrup church is from around 1150, indicating that a well-established community was already found at the site at this point.

Most of the privately owned land came under Roskilde Cathedral over the next couple of centuries but was confiscated by the Crown after the Reformation in 1536.

The growing population combined with the already miserable living conditions in the central city led to a series of national plans to expand the number of housing units.
