Diocese of Sigtuna

A Diocese of Sigtuna was founded in the middle of the 11th century, when the town of Sigtuna, north of Lake Mälaren and south of Uppsala in the Swedish province of Uppland, had been the centre of Royal power for some decades, and existed until the middle of the 12th century. It was eventually out-competed by the earlier pagan religious centre Gamla Uppsala (Old Uppsala), which was raised to the status of archbishopric in 1164 (see: Archdiocese of Uppsala).
