With the construction of the Herford-Lage-Detmold railway lines in 1880, Lage-Lemgo in 1896 and Lage-Bielefeld in 1904, Lage became a traffic junction in the Lippe region. Opposite a first simple single-storey station building was a meadow area criss-crossed by beaten paths. There was a wide ditch with a wooden bridge between the meadow and the train station.
The construction of a new train station at the end of the 19th century initiated a planned urban development. In the center of a newly emerging road network was the Sedanplatz park opposite the train station. In the 20s of the 20th century, the western expansion of the city with the construction of houses, factories and administrative buildings was largely complete.
A chestnut avenue was laid out between the train station and the main road Bad Salzuflen - Lage - Lemgo to the north.
In the first half of the 20th century, the forecourts of the larger train stations in the region were mainly designed as elaborate decorative areas with representative driveways, flower circles, monuments and lights. While the rest of the station forecourt in the region was redesigned and fortified from 1950 at the latest according to traffic considerations, the area in Lage was largely spared from this development. Photos from the early 1960s show a square with a hedge-lined geometric network of paths, rows of trees, flower borders and roundels, and a fountain. Probably mainly in the 1970s, these representative elements were pushed back in favor of today's easy-care lawn.
