The Stalingrad-Lemonnier district is squeezed in a vice between the inner ring road, the Nord-Midi railway line and the historic city centre. This part of the Pentagon has been a centre of commercial activity since the nineteenth century. Subjected to upheaval many times by major urban planning projects in the twentieth century, the district has recently been renovated by the government and today is once again confronted with large-scale infrastructure works: the construction of the North metro launched in 2020 by the Brussels-Capital Region and STIB. This latest upheaval could well threaten the very existence of the businesses around Avenue de Stalingrad. ARAU thus offers a reminder of the district’s rich history and is meeting places, so as to better understand the battle being fought today by its residents.
