Modena. The Darsena was excavated, north of Porta Albareto or Porta Castello. It was an extension of the Naviglio canal where boats paid tolls. Alongside the canal ran Via Alzaia, while in Modena it was Via Attiraglio, which took its name from the dragging (“tiraglio”) of boats toward Modena (against the current) by oxen or horses. The ducal boats took three days to reach Venice along the Naviglio and then the Panaro and Po rivers; a full six days for the opposite journey against the current.
