Delubrum is a term used in ancient Rome to refer to a temple or a shrine. It's a Latin word that isn't commonly used in modern English, but there are a number of words that can be used as synonyms for it. These include "sanctuary," "holy place," "sacred space," "sacred chamber," "shrine," "sanctum," and "holy of holies." Each of these words can be used to describe a place that is considered to be sacred and dedicated to a particular divinity or religious purpose. Whether ancient or modern, each of these words conjures up the idea of a sacred site that is considered holy and revered.
