Riddarfjärden
Riddarfjärden (, "The Knight Firth") is the easternmost bay of Lake Mälaren in central Stockholm. Stockholm was founded in 1252 on an island in the stream where Lake Mälaren (from the west) drains into the Baltic Sea (to the east); today the island is called Stadsholmen and constitutes Stockholm's Old Town.
Gamla stan
The name Stockholm originally referred to Gamla Stan only, but as the city expanded, the name now also refers several suburban areas and the metro region. The name Stockholm means "log island" in Swedish. The previous capital of Sweden was located in Sigtuna. A thousand years ago Sigtuna had problems with armed gangs attacking the city. The situation became untenable and there was a need to find a new location for the capital city of Sweden. According to legend the leaders in Sigtuna then took a log of wood, cut out all the wood inside, filled it with gold, and let it float on the water. The log was floating on the water for several days and eventually hit land on the island where Gamla Stan today is located. The island was named Stockholm or log island, meaning the place where the log had hit ground. This is where they decided to found the new capital of Sweden. The island of Stockholm had the advantage that it was an island, easy to defend from armed gangs that could be thought to want to attack the city. It also had the advantage from a trade point of view, that it was situated just at the inlet of Lake Mälaren, a big lake very important to contemporary trade, from the Baltic. A sculpture symbolizing the old log is today found at Stadshuset, the Stockholm City Hall.
