Marinarkeologi i Motala Ström, Norrköping: week 1

This week Bohusläns museums maritime archaeologists have been in Norrköping conducting an archaeological survey in Motala ström, Norrköpings hamn. The weeks plan was to map the survey area east of the bridge  using our scanning sonar and also to dig test pits along the nothern wharf at regular intervals.

During the week we mapped the entire survey area west of the bridge with our MS1000 scanning sonar and dug 10 test pits. Diving on sonar anomalies, continued survey and test pit excavating on the western side of the bridge, will continue  during week two.

Norrköping is a city that has its beginning in the middle ages. One of the first maps we have is from Johan de Rogier which depicts close lying buildings and the 1600s castle Johannisborg.

Motala ström has also been a major route for transport in to Nörrköping. This is evidenced amongst other references on a map from 1695. One can plainly see vessels that are using Motal ström for transport. Also the island below Johannisborg is called skeppsholmen. Skeppsholmen today is not an island since the passages on its northern shores have been reclaimed.

Last but not least Norköping has had a working port from at least the early 1800s. In the map below one can see that skeppsholmen is still partly surrounded by water and that an area called ‘Gamla Varvet’, the old wharf is depicted.
