Archaeological excavations in the 20th century unveiled ships and landing bridges under the present streets — today located more than 500 metres (1.600 feet) from the waterfront.
The second water course was the strait Näckströmmen ("The Neck Stream") which separated Blasieholmen (at the time an island) from the mainland north of it.
In 1816, City Architect Carl Christopher Gjörwell was commissioned to redesign the quays of the bay, plans however only partly completed.
Packartorgsviken became gradually smaller and swampier, and was colloquially called Katthavet ("The Cat Sea"), with Katt alluding to something small and false (i.e. a water body of insignificant size).
[2] Fathomless to today's Stockholmers, Katthavet remained a popular spot for angling and pleasure rowing — truly an odd hobby as the filthy bay was also used for cleaning clothes.
By the end of that decade, however, the 25th anniversary of King Charles XIV's arrival to Stockholm resulted in plans for a new bridge across the bay.
