Bulle is a municipality in the district of Gruyère in the canton of Fribourg in Switzerland. In January 2006 Bulle incorporated the formerly independent municipality of La Tour-de-Trême. Downtown Bulle is made up of many shops such as Yendi and Blackout, and offices, a train/bus station (with regular service to nearby Fribourg), and an old chateau that was converted into a prison. A sculpture of a bull sits in a traffic circle by the bus station, showing the emblematic animal for which Bulle is named.
