Nyau Festival Dedza in Dedza
Nyau Festival Dedza is associated with Dedza, a highland town in central Malawi close to the Chongoni Rock Art Area, a UNESCO World Heritage site linked to Chewa ritual and rain-making traditions. A festival by this name would plausibly showcase gule wamkulu, the masked dance of the Chewa Nyau society, though independent confirmation of the specific event's organisers, dates and format could not be found.
Dedza district, in the highlands of central Malawi close to the Mozambique border, is one of the country's most culturally significant Chewa areas.
