The history of Sigtuna before the 11th century, as described in the Norse sagas and other early medieval sources, can be found in the article Old Sigtuna.
Sigtuna has a picturesque medieval town centre with restaurants, cafes and small shops. The old church ruins, runic stones and "Stora Gatan" (Main Street) are popular attractions for tourists especially in summertime. The small streets with the low built wooden houses lead up to several handicrafts shops and the old tiny city hall, Sigtuna R�dhus. There are restaurants and a hotel (Stadshotellet) in the town centre
