Strömsborg

Administratively, Strömsborg is part of Gamla stan, the old town of Stockholm and is connected to the rest of the city by the bridge Strömsborgsbron leading over to Vasabron.

Further, Nordensvan tells the island has been the site for several restaurants, skittle alleys, and public baths, and "was a small idyllic spot, particularly at that time, when no bridge led to the islet, but one had to travel by rowing boat with a motley woman from Dalarna at the oars.

[8] Known for centuries as a set of insignificant cliffs surrounded by a number of treacherous sunken rocks, Strömsborg is represented on Petrus Tillæus' 1733 map as uninhabited and named Stenskär ("Stone Skerry").

For example, in 1747 Tillæus mentions it as det stenskär eller klippa som är beläget uti Norra Ström och Melaren ("the stone skerry or cliff that is located in Northern Stream and Mälaren") and says it occupied an area of 2.944 square ells (kv.alnar) in size.

In a letter in 1647 Queen Christina donated the island to her half-brother and referred to it as den lille holmen eller skäret ("the small islet or skerry").
