In the middle of the nineteenth century, a new railway line was built in eastern Brussels to link Brussels-North station to Brussels-Luxembourg station. However, it quickly became seen as an obstacle to the urban growth of the booming Schaerbeek and Saint-Josse-ten-Noode districts, and so it was moved and buried underground at the turn of the century. The railway line significantly marked these districts and created an unusual cityscape. ARAU offers you an opportunity to follow the traces of this railway line through several groups of remarkable heritage buildings, including the Squares district in Brussels, Square Armand Steurs in Saint-Josse and the Avenue Paul Deschanel in Schaerbeek. You will learn about the influence the railway had on the development of these districts, and see places where the former “frontier” formed by the railway is still visible.
