A columbarium (/ˌkɒləmˈbɛəri.əm/;[1] pl. columbaria) is a structure for the respectful and usually public storage of funerary urns, holding cremated remains of the deceased.

The term can also mean the nesting boxes of pigeons. The term comes from the Latin "columba" (dove) and, originally, solely referred to compartmentalized housing for doves and pigeons called a dovecote.
