The gutters of Den Gamle By are free from the filth of the past.
Unsanitary streets
Drainage of wastewater
Along the houses in Algade there is a channel in the cobblestones designed to carry rainwater and wastewater away from the streets. This is called a gutter (rende). In the past, however, it was filled with so much filth—including human waste—that it would frequently become blocked.
Dirt and filth in the streets
In the towns of the 17th and 18th centuries, the streets were so full of animal and human waste that it could be directly hazardous to public health. In 1787, Vestergade in Aarhus was described as: “... more a manure pool than a market town street.”
Some streets were even named after the filth: Horsens had Skidengyde, Sønderborg had Møggade, and Ribe had Skidenslippe. In Maribo, Skidenstræde still exists today (as of 2016).
