Columbarium:
A columbarium (pl. columbaria) is a place for the respectful and usually public storage of cinerary urns (i.e., urns holding a deceased’s cremated remains). The term comes from the Latin “columba” (dove) and originally referred to compartmentalized housing for doves and pigeons called a dovecote. [Wikipedia]
