Binnendieze is the common name for the river and canal system within the city walls of 's-Hertogenbosch, the Netherlands. It is a tourist attraction. Near the north-west tip of the city walls, the confluence of the Binnendieze with the rivers Aa and Dommel forms the short river Dieze, tributary of the Meuse ().
Dieze and Dommel
The Dommel originates in Belgium and flows through Eindhoven and 's-Hertogenbosch to join the Meuse. However, inside 's-Hertogenbosch and further downstream, the Dommel is known as (Binnen)Dieze. This has historic reasons. In the past, locals considered the Esschestroom, or Run, which runs from Oisterwijk to Halder, to be the main stream bed of the Dommel. Therefore they applied the name 'Dieze' to the whole stretch between Oisterwijk and the Meuse.
When the Dommel came to be considered the main river, the stretch of the Dieze between Oisterwijk and Halder was renamed Esschestroom, or Run. The stretch between Halder and 's-Hertogenbosch was renamed Dommel. Within the gates of 's-Hertogenbosch however, the Dommel retained the name 'Dieze', later changed to 'Binnendieze'.
When the fortifications of 's-Hertogenbosch were dismantled in the 1870s, the main stream bed of the Dommel was rerouted to the west of the city. It created the 'Nieuwe Dommel', which is now simply known as Dommel. It runs a more or less 'parallel' route with the 'Dieze'. The operation also created a new confluence of the Dommel with (a diversion of) the Aa. From a local perspective, however, these artificial diversions joined the Dieze, which was already flowing from the city harbor of 's-Hertogenbosch to the Meuse.
The Binnendieze
The natural situation The part of the Dieze inside 's-Hertogenbosch is known as Binnendieze, or inner Dieze. Before human intervention, the Dommel flowed to the east of the town and made a bend south and east of the Windmolenberg (a natural height). It then continued to where the Hinthamereinde now is. Here it joined the Aa, where now the western door of 'Sluis 0' (a lock) is situated. Together they then flowed west again.
The Groote Hekel
When the second city wall was built in the fourteenth century, the confluence of the Dieze and the Aa came to lay inside the city walls. Another junction, the split of the Dieze and its runoff Verwerstroom, also came to lay within these walls. Just south of this split a water gate was built. It is named Groote Hekel, after the beams (Hekels) that blocked the water gates. From the Groote Hekel the main course Groote Stroom flows east, the smaller Verwerstroom flows west. Both became known as Binnendieze. However, the name was also applied to other streams in the city. Some of these were arms of the Dieze, others were artificially connected to it.
The water gate Groote Hekel was first mentioned in 1399. It originally had three gates, and was hence known as 'De Drie Hekelen'. It gave barges from the Dommel access to the city, and drained access water from the Bossche Broek. The westernmost gate was walled up from 1634 to 1668, probably to drain off less water from the militarily important Bossche Broek. Before 1880 the gates could be blocked against enemies, but could not block the water of the Dommel.
In 1880 a double lock was built on the outside of the two remaining gates. Therefore the medieval gates can only be seen from inside the city walls. While viewing these, another row of two big gates and one smaller gate is visible immediately east of the two remaining water gates. These are remains of a steam-powered pumping station built in the early 1880s, and broken up in 1965.
Groote Stroom
The original main course of the Binnendieze is known as Groote Stroom. It starts at the Groote Hekel in the southern city wall, and then bends to the east, before flowing back to the west, where it joins the city harbor at Jan Heins street. The complete course is difficult to discern because in 1962 the Marktroom and old city moat were filled up. There were also earlier interventions in its course.
When the first city wall was built in the early thirteenth century, part of the natural stream bed of the east-west stretch of the Grote Stroom (called Marktstroom) came to lay within the city walls. In the wall the current water gate was made. East of it, the Grote Stroom was diverted and led through the northern moat. The next major interference was a connection between the Grote Stroom and the Vughterstroom north of the first city walls. This was achieved by digging the stretch that now runs along the Jan Heinsstraat, probably in 1250-1275. In 1300-1319 a large bend of the Groote Stroom was cut off. It led to the construction of the Geerlingse bridge in the Hinthamer street.
The Groote Stroom has some of the most spectacular sights of the Binnendieze. The water gate in the first city wall is one of these. It is remarkable that such a gate, that was superseded by later buildings, survived. Its location was crucial, because it could only be reached by water. This gate has grooves where beams could be inserted to stop the water of the Dieze. It is not clear whether there was a relation with the absence of such capabilities at the Grote Hekel.
Doode Stroom
The Doode Stroom is a filled up part of the bend which was cut off from the Groote Stroom in 1300–1319. This bend continued to exist for over 500 years. The northern part continued to be the connection between the Aa and the remaining Grote Stroom as it now exists. The southern part led through a quite part of town. During the construction of the second city wall in the fourteenth century, a water gate called 'Kleine Hekel' was built. It enabled barges from the Aa to enter the city, and to continue on the northern stretch. A diversion of the Aa was made to feed the new northern city moats. The southern stretch gradually started to disappear from the maps in the eighteenth century.
During the construction of the Zuid-Willemsvaart in the 1820s, the Kleine Hekel north of this canal, was demolished, and the stretch of the Binnendieze from the Kleine Hekel to the Groote Stroom was cut off from the Aa. Hence it became known as 'Doode Stroom' (dead stream). The Doode Stroom did not receive much fresh water, and therefore began to stink. It was one of the first streams that got a sewer and was filled up, the small part east of 'Achter de Mollen' in 1922, the rest in 1929.
In 2018 urban development led to an unlikely rediscovery of the Doode Stroom close to the Zuid Willemsvaart. Below the Europeesch Keramisch Werk Centrum (EKWC) a cellar was found that contained the quay walls and the intact former bridge of the ally Achter de Mollen. It turned out that after the stream had been diverted through a tube, the stream had simply been bridged by steel beams covered by masonry. The municipality and the project developer immediately conferred to profit from this circumstance. Making the small bridge visible would be good for tourism, but would also significantly increase the price of buildings on the premises. By mid-2020 the project was still in progress.
Verwerstroom
The Verwerstroom is a natural, smaller branch of the Dommel / Dieze. It splits off from this river immediately behind the city walls at the Groote Hekel. The part of the Verwerstroom between the Groote Hekel and the Noordbrabants Museum follows a (natural) river bed. Here street names like Verwerstraat, Volderstraatje and Raamstraatje (no name plate) remind of woolen cloth-making. 'Verwer' is Dutch for someone who dyes cloth. Fulling () was a dirty job to felt woolen cloth. After that cloth had to be rinsed out and was made to dry on racks ().
The part north of the museum, north of the junction with the 'Kleine Vughterstroom' was dug to bring water to the first city walls. It continues along these former walls towards the north-west, along the Snellestraat. Just north of the junction of the Snellestraat and the Postelstraat, the Verwerstroom abruptly turns west. All this establishes a connection from the Groote Hekel to the city harbor, which is fed by the Vughterstroom.
The original confluence of the Verwerstroom with the Vughterstroom was at the Visbrug. When the second city wall was built in the second half of the fourteenth century, the stretch of the Verwerstroom along the Kruisstraat from its last bend near Guardianenhof till the Visbrug was filled up. This explains the unnatural bend at Guardianenhof. It also explains the north arch in the Visbrug. This is the original exit of the Verwerstroom, which was made visible again in 1976.
Nowadays the southern part of the Verwerstroom can be viewed from bridges on the Zuidwal, Volderstraatje, Beurdsestraat, Oud Bogardenstraatje, Paradijsstraaje, the Waterstraat (Noordbrabants Museum), and Klein Lombardje. The highlight of this part of the Verwerstroom is its passage right before the facade of the Noordbrabants Museum. In the Snellestraat it is only visible in two places. At Guardianenhof there is a view of the Verwerstroom that shows that it changes course by flowing under a bridge in the Postelstraat. Indeed the prime attraction of the Verwerstroom and other parts of the Binnendieze, is that houses were built over it. It means that the Verwerstroom can still be navigated, but is hardly visible from the street.
Vughterstroom
The brook Vughterstroom started as an arm of the Dommel at the height of Fortress St Anthony. It then continued west of the city, probably in a bed between the current Dommel and the railway station. It touched the city again where the citadel now is. From there, it roughly followed the course of the present Dieze. Before the Dieze was 'created' in the fifteenth century, the main course of the Dommel/Dieze streamed way east of it. The Vughterstroom joined this course way north of the city, probably near Engelen.
In the thirteenth century (probably 1250-1275), the sand ridge to the west of the Grote Stroom was dug through, creating a connection from a bend in the Vughterstroom to the Groote Stroom. The city then started to dig towards the south till the Korenbrugstraat to create a harbor. The natural Vughterstroom had to be diverted through this harbor to keep it deep enough. Therefore a canal was dug south of the Korenbrugstraat till it met the natural Vughterstroom between Lamstraatje and Capucijnenpoort. The dug stretch from the harbor together with the natural upstream part till its junction with the Kleine Vughterstroom, is now called Vughterstroom. When the second city wall was built in the fourteenth century, the Vughterstroom came to lay inside the walls, with a water gate on the Kuipertjeswal. The natural part south of the junction with the Kleine Vughterstroom, including the water gate has been filled up.
The Vughterstroom is now one of the most famous parts of the 'Binnendieze'. The street that runs alongside it is very quiet and has many views on the water. The northern part has many cafés, restaurants and terraces. This is also one of the starting points for the popular boat trips on the Binnendieze.
Kerkstroom
The Kerkstroom is named for flowing under the choir of St. Catherine's Church. It is a short natural stream that exits into the Kleine Vughterstroom. From the city moat there are two entrances to the Kerkstroom. Both are called Kruisbroedershekel. The old Kruisbroedershekel was rather narrow, but nevertheless required a 'Hekel' to close it. It was only in 1880 that it was transformed into a sluice. The new Kruisbroedershekel dates from 2002, and was made to (again?) give boats access to the Kerkstroom. From a low hole in the wall west of the old Hekel, a corridor starts through the walls. Inside a room was made which shows the fourteenth-century second city wall and a 16th-century gate which was found during construction. The corridor continues to exit in the Kerkstroom just behind the wall.
