Tomb (6)
I believe the answer is:
shrine
'tomb' is the definition.
(shrine can mean a tomb or memorial)
This is all the clue.
(Other definitions for shrine that I've seen before include "Holy site of relics etc" , "Place hallowed for special associations" , "Casket with holy relics" , "Hallowed place associated with a sacred thing or person" , "temple" .)
