Meszes-köz Bridge. This crossing over the creek most likely dates back to the Middle Ages as this was the shortest route from Káptalan sor, currently Knézich Károly utca, to the centre of the town. Starting from the 18th century, the butchers’ houses stood here along the left side of the creek, releasing a lot of waste into the creek in this area. Thus it is important to mention the cleanness of the creek as, since the 18th century, the purity of the water was a continuous problem for the city council given that the water course flowing along the whole length of the settlement served several functions at the same time. The most efficient way to secure the good quality of the water of the creek was by also taking care of the cleanliness of the streets since with rainwater, the garbage and filth on the streets poured towards low-lying areas, namely the creek. The water quality of the creek was endangered not only by the filthy streets but certain trades as well. Leather tanners, for instance, when finishing hides, would wash the leather in the creek, thus heavily contaminating the water. Butchers, however, operated in the middle of the city. Several of the slaughterhouses were located along the creek, in Meszes-köz – current Gerl Mátyás utca and the area of the parking lot towards the creek – with slaughter and sale of meat taking place in one place, thus meat was less likely to go off quickly. However, contamination from the slaughter of animals flowed into the creek.
