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.
Birger Jarls torg
The square used to be called "Riddarholmstorget", but was in the mid-19th century renamed "Birger Jarls torg" after Birger Jarl, traditionally attributed as the founder of Stockholm. A statue of him was erected on the square in 1854.
