BUTARE           The town of Butare situated 135 kms south of the capital Kigali, was and still is considered Rwanda´s cultural and intellectual pulse. The national university and various institutions of higher learning are situated here but the most prominent attraction is the superb National Museum with perhaps the finest ethnographic collection in East Africa.           Butare´s cultural significance is further underlined by a visit to nearby Nyanza, the traditional seat of Rwanda´s ancient feudal monarchy.
