A memorial pole, also known as hollow log coffin, burial pole, lorrkkon, ḻarrakitj, or ḏupun, is a hollow tree trunk decorated with elaborate designs, made by the Yolngu and Bininj peoples of Arnhem Land in the Northern Territory of Australia. Originally used to hold the bones of deceased people or for burial ceremonies, they are now made as works of art. The permanent exhibit at the National Gallery of Australia, Aboriginal Memorial, consists of 200 hollow log coffins, created by 43 artists.
