Sigtuna is a town in Sweden, not far from Stockholm and Uppsala. The town was most important during the tenth through thirteenth centuries as a royal and commercial center, but eventually dwindled in size.
In the winter 1930, men claiming to be from the Swedish National Museum in Sigtuna met with Dr. Theresa Lawrence on a flight from Marrakesh after she had obtained the Uppsala Scroll from her partner, Indiana Jones, who had stolen it from Rene Belloq. She gave these men the scroll, hoping to show that she, as a representative of the British Museum, was not a grave robber. Unfortunately as Jones mentioned to Marcus Brody afterward, the Swedish National Museum was in Stockholm and not Sigtuna, meaning that these men were not who they claimed to be - and the scroll was gone.
