1.37 mile street circuit. However, another street circuit was used in the 1960s,
and this is shown below.
This track was used between 1960 and 1962 for non-championship F1 events.
The lap distance in 1960 was 2.7 miles, but in 1961 they replaced the sharp
corner at the top right of the map with a route around the roundabout instead,
lengthening the lap distance to 2.83 miles.
3.7 km track around the centre of Brussels, used in 1946.
Used for the 2nd Grand Prix de la Cambre in 1946. Note that the above
circuit shares part of the same road as the previous variant - not sure if
both were used, or only one was.
