Many Pagans embrace the idea that the universe is enchanted; that even the most mundane and ordinary elements of nature are, at least potentially, pregnant with spiritual power and possibility. Taken to its pantheistic or monistic extreme, Paganism celebrates all space - all of nature - as sacred or holy. But within that framework of overall immanence, particular sites or points within the natural world are revered as places of special spiritual power and worthy of reverence and veneration.
Stonehenge, Angkor Wat, Newgrange, The Pyramids of Egypt, Macchu Picchu, the Parthenon, the Great Serpent Mound - all over the world, numerous sites of ancient ceremonial and religious significance remain today as mysterious mute testaments to prehistoric or ancient spirituality. Pagans often look to such venerable monuments for inspiration in the continuing quest to revive or recreate polytheistic, goddess-centered, or earth-based devotion.
Such human-made sites often are subject to a variety of different interpretations. Some are burial grounds; others appear to be giant observatories; still others have no clear religious or ceremonial meaning. Prehistoric sites are often the subject of imaginative speculation as different theorists offer their interpretation as to the original or ultimate meaning and purpose of such sites.
In addition to sites that were clearly fashioned by human hands, other remarkable or distinctive sites throughout the earth have become subject to spiritual devotion, often because of distinguishing geographic features, but also because of metaphysical beliefs associated with such sites. Glastonbury Tor in England, the Black Hills of South Dakota, and Ki l a u e a in Hawaii are examples of spectacular sacred sites, while many less dramatic sites may be centers of regional or local veneration, such as the tradition of holy well veneration in the Celtic countries.
Such sites typically achieve status as "sacred" in the minds of devotees because of historical significance, particularly in regard to mythology or folklore. Sites associated with ancient gods or goddesses carry special significance even for latter-day Pagans. Remarkable trees, abundant water sources, and other singular features of the earth can be imbued with meaning, either received through folklore or local tradition, or even established by contemporary Pagan individuals or groups who feel drawn to find or create spiritual meaning through relationship with a particular feature of the natural world.
In addition to such physical forms of sacred space, Pagan traditions often also include metaphysical or imaginal forms of sacrality as well. These include mythic concepts of the otherworld, ritually created sacred space (such as the Wiccan "World Between the Worlds"), and even the concept of sacred space as found within each individual's own capacity for inner visualization.
Concepts of the otherworld can take many forms. Nonmaterial realms may exist above, below, or interwoven with the material world. They can exist in a variety of metaphorical locations, such as over or beneath the ocean, through the mist, or within so-called hollow hills ("fairy mounds"). The otherworld can be a place of ineffable beauty and wonder, but also a realm fraught with danger and challenge. It can be populated with gods, goddesses, ancestors, heroes and heroines, as well as spirits, elves, fairies, or other entities seen as intimately connected with nature.
Sometimes human beings can visit otherworldly realms, although myths are often vague about how such a journey can occur. Once in the otherworld, the human visitor may have a quest or sacred task to complete, may be held prisoner, or may fall in love with a beautiful otherworldly figure and then face a terrible choice between remaining with the lover or returning home to the mundane realm.
Perhaps such "otherworlds" only exist in human imagination - but even so, they can be meaningful elements within an individual's or a group's spiritual practice. Such forays into the realm of mythic imagination can be experienced as challenging, healing, inspirational, or deeply transformational.
Many Pagan groups and individuals engage in magical ritual practices as part of their spiritual life. Such rituals can be devotional in nature (offering love, honor, and worship to gods, ancestors, or nature spirits) or thaumaturgical (attempting to create real change in the world through magical means). In some Pagan traditions, performing a sacred ritual involves establishing a bounded space (often a circle) in which the energy of the ceremony occurs. This space is understood as having a magical quality that sets it apart from the rest of the physical universe. In Wicca, for example, such magically inscribed ritual circles are said to create a world "between the worlds" - a spiritual locus between the material and the spiritual realms, allowing access to both planes. Unlike other faith traditions where rituals need to be performed in relation to a specific physical location (such as a church or a temple), the magical circle is, in essence, a portable sacred space that can by psychically created with each new ritual and then dismantled when the ritual is finished.
