This walk offers the opportunity to follow in the footsteps of the Senne river within the so-called Pentagon, following the trail of recent archaeological excavations by, but also older discoveries. Although the Senne disappeared from the urban landscape after it was vaulted during the second half of the 19th century, it nevertheless left a lasting mark on the city centre. Indissociable from the origins of Brussels, where the existence of a harbour (portus) is attested as early as the 11th century, the river plays a major role both in urban planning and in craft and industrial activities. It was an important waterway until the Willebroek Canal was opened in 1561. The walk will follow the river from its entrance through the Grande Écluse (Great Lock), through the second city wall of the 14th century, right to its exit through the 13th century first city wall, in the vicinity of the Black Tower (St Catherine’s Square).
