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.
Museum of Medieval Stockholm
The museum enables visitors to experience medieval Stockholm, with its brick houses and booths, workshops, harbour and gallows. It relates the medieval history of the city from the 1250s to the 1520s. In 2010, to celebrate 800 years since the birth of Birger Jarl, the founder of Stockholm, the museum opened an exhibition with a reconstruction of his face.
