The Havana Foundation Anniversary is observed in Havana, Cuba, every November 16, celebrating the city's rich historical and cultural heritage. This occasion marks the re-establishment of San Cristóbal de la Habana in its current location in 1519 by Spanish conquistador Diego Velasquez. Although not a public holiday, residents honor the anniversary with various festive events. A notable custom involves locals walking around a revered ceiba tree, believed to be the site of the first town council meeting and religious mass, three times in silence while touching the trunk and dropping a coin at each turn. This ritual symbolizes the fulfillment of wishes or gratitude for past blessings. The event is sometimes mistakenly referred to as Saint Cristóbal Day, despite the Catholic Church celebrating Saint Christopher's feast day on July 25, which is unrelated to the foundation anniversary.
