About Grand-Place in March
The Grand-Place area sits at the lowest point of the old Senne river valley, making it Brussels' most fog-prone neighborhood — cold air pools here on still winter nights, and humidity lingers well into the morning. The dense medieval-to-baroque stone fabric retains heat in summer, creating a strong nocturnal urban heat island effect despite narrow shaded streets.
