Tambu Heritage Festival Curacao in Willemstad/national
Curacao's tambu tradition, an Afro-Curacaoan music and ritual practice legally banned from 1936 to 1952 with full restrictions lifted only in 2012, is documented and preserved through the Museo di Tambu Shon Cola and featured within Siman di Kultura's musical heritage programming; a separately confirmed standalone Tambu Heritage Festival could not be verified.
Between 1936 and 1952, colonial authorities on Curacao made tambu, an Afro-Curacaoan tradition of music, dance and communal ritual dating to the mid-seventeenth century, an outright illegal act, destroying instruments and threatening participants with exclusion from Catholic Mass simply for attending a gathering.
