Besides the music and dancing, Congo Square also provided enslaved blacks with a place in which they could express themselves spiritually. This brief religious freedom on Sundays resulted in the practice of voodoo ceremonies. Voodoo is an ancient religion that developed from enslaved West Africans who brought this ritualistic practice with them when they arrived in New Orleans in the 18th century. Although it is not the most noted recreational activity people took part in at Congo Square, it was nevertheless one of the many forms of entertainment and social gatherings here. Voodoo was the most prominent from the 1820s to the 1860s, as Congo Square provided an opportunity to expose people to this intriguing practice.
