Knives and daggers, along with some axes, swords, and spears, were revealed during the excavations as well.
The archaeologists believe the weapons were discarded due to regulations or a ban on weapons or long blades.
Similar regulations had been established in other medieval cities. The prohibition might point to a form of customs control at the harbor.
Medieval Oslo is not fully understood because many Norwegian documents were lost during a fire in 1728.
The city’s medieval laws were also not preserved. However, the recent excavations may help shed light on the city’s past.
