The earliest historical references to coinage and trade guilds in Sweden mention Sigtuna. In 1187 the city was plundered and burned by neighboring pagans, after which it lost its importance.
Architectural monuments in Sigtuna include the Romanesque tower of St. Lars (approximately 1100) and the brick Gothic St. Maria Church (13th century). In the center of the city are 18th-century wooden buildings, including a town hall.
