Take a walk around Riddarkyrkan
One of the oldest, if not the oldest church in Sweden still standing. The original building was put up in the middle-late 13th Century, and became the Royal Church with the Royal Families from that time to the (almost) present buried in vaults that have been added to the original as time progressed.
This 13th century church is the final resting place of swedish Monarchs starting with Gustav Aldohus (1632).
The Northern facade of Riddarholmskyrkan comes on Birger Jarls Torg square.
The monument to the founder of the city Birger Jarls is established in the centre of the square.
