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.
Great Stockholm Fire of 1625
The Great Stockholm Fire of 1625 was among the first known large scale fires in Stockholm prior to the city plan changes of the 17th-century. The fire began in the evening of September 1, 1625 in Kåkbrinken, and devastated the southwestern parts of Stadsholmen. It lasted three days and reportedly destroyed a fifth of the infrastructure of Stockholm at the time. The fire resulted in the building of a new city over the burnt areas, and a new tightened organisation of inspection of the fire prevention measures in the city.
