I believe the answer is:
shrine
(Other definitions for shrine that I've seen before include "Tomb or monument of a saint" , "Hallowed place with religious association (6)" , "Hallowed place associated with a sacred thing or person" , "Casket with holy relics" , "Place of worship associated with a revered person" .)
