Bulle

Bulle is a municipality and the district capital of Gruyère in the canton of Fribourg in Switzerland, built on a hill at an elevation of 770 metres above the left side of the Trême river. The settlement is first mentioned in the 9th century as Butulum and was long the home of a large parish church dedicated to St. Eusebius. Bishop Boniface of Lausanne had a city wall built around a rectangular town in 1231 to 1239, and Bulle was already an important regional market centre by the 12th century, when the counts of Gruyères and the bishop contested its rights. In January 2006 it absorbed the formerly independent municipality of La Tour-de-Trême. It covers 23.86 square kilometres and had 24,412 inhabitants in December 2020, most of whom speak French.
