What it is
The pair of one-way roads on the two banks of the moat: the outer bank runs clockwise, the inner counter-clockwise, so that the square is a roundabout 6.54 km round. The municipality built the roads in 1948, demolishing stretches of the wall to do it. The year the one-way system began is not on this disk.
The long version
Inference — the loop is the city's first ring and its smallest, and the only one that is not a bypass: it does not take traffic round the centre, it takes traffic round the centre's edge and lets it in at the gates and the corners. A driver who misses a turn drives the whole square again. Everyone who has lived here has done it.
The story page argues what the loop did to the old city; the measurements page counts what is inside it.
