Junkanoo (the heritage Bahamian carnival, performed Boxing Day December 26 and New Year's Day on Bay Street since the 17th century — origins in the slave-era period when slaves were granted three days off around Christmas, masked-and-feathered procession with goatskin drums, brass bands, whistles, cowbells, and the heritage glittered crepe-paper costumes built by neighborhood Junkanoo groups for months ahead) is the Bahamian cultural signature. Major groups: the Saxons Superstars, the Roots, the Valley Boys, One Family. The Junkanoo Beach + Festival Place hold off-season demonstrations and the Educulture Junkanoo Museum (the heritage Junkanoo museum on West Street, by Arlene Nash Ferguson) shows year-round costume + history.
