Sigtuna is a small town about 40 kilometers northwest of Stockholm. This romantic town is the oldest in Sweden, a little over 1000 years old. This town played the role of an economic and royal center for over 250 years since its founding, even the first Swedish coins were minted in Sigtuna around 1000 AD. It began to lose its significance during the 13th century when there was a post-glacial rebound, which closed the important waterways that connected Sigtuna with the sea. Sigtuna, a town of 600 people, experienced its partial renaissance in the second half of the 20th century due to the construction of an airport not far from Sigtuna when the population grew to over 8000 inhabitants.
