Sacred sites are places of religious or spiritual significance, often associated with a particular deity or belief system. Holies, shrines, and sanctums are all examples of sacred sites. Holies are typically places of worship, such as churches, temples, or mosques. Shrines are usually dedicated to a particular figure or event, and may contain relics or other objects of veneration. Sanctums are often considered the most sacred of all sites, and are usually reserved for special ceremonies or rituals.
