The Catedral de la Virgen María de la Concepción Inmaculada de La Habana (Cathedral of The Virgin Mary of the Immaculate Conception) is a Roman Catholic Cathedral and is the seat of Jaime Lucas Ortega y Alamino, the Cardinal Archbishop of Havana, Cuba. It was constructed by Jesuits (1748–77) on the site of an earlier church. It is also dedicated to Saint Christopher (San Cristóbal), thus it is sometimes dubbed as Cathedral of Saint Christopher.
Set in the former Plaza de La Ciénaga or Swamp Plaza, the Cathedral is said to be the only example of a baroque facade that was designed with asymmetrical features - one of the towers is wider than the other. This particular feature was conceived in order to allow the water that tended to accumulate on the plaza to freely flow through the streets during the colonial period, when it was built.
Cuban writer Alejo Carpentier famously described the Cathedral as "music set in stone". It is the most prominent building on the Plaza de la Catedral, in Old Havana.
