Born in Transylvania, the mystic leader of Doomsday Cult of 40 Monks, awaiting the apocalypse
in the year 1700...

Tucked away in a remote section of Philadelphia’s Fairmount Park, you’ll find the “Kelpius Cave,” an enhanced cave built into the side of a hill, with a stone frame entrance marking what’s believed to be the 17th century home of America’s first cult of mystics to predict

the imminent apocalypse. tradition holds that this area along the banks of Wissahickon Creek was settled in 1694 by mystic and scholar Johannes Kelpius and his followers. Believing, based on elaborate interpretation of the Bible’s “Book of Revelation,” that the world was going to end that year, the monks sought to live a solitary lifestyle in the wilderness while awaiting the End of Days and the Second Coming. The group was known as “Hermits of the Wissahickon,” or “The Society of the Woman of the Wilderness”—the latter a reference to a passage in “Revelation” in which a woman flees to the wilderness to seek refuge from the end of the world. Following this example, the monks (all of whom were men) established themselves on a hill at the edge of the Wissahickon woods. The area was known as Hermit’s Glen; today, a nearby road called Hermit Lane gives a nod to the area’s occult history. These early Pietist monks fled their home country of Germany to the newly founded province of Philadelphia, which was built on the principle of religious tolerance and which already had a large Quaker population. (There is a statue of a man in Quaker garb called “Toleration” in the Wissahickon as well, 40 minutes north of the cave by foot, that watches over the valley). Kelpius, Philadelphia’s first mystical guru, hailed from Transylvania and was 26 years old when he formed the Society here in the woods. He was a musician, scholar and writer, interested in botany and astronomy. Indeed, many of the monks practiced medicine and composed music while they waiting out the end of days. They’re thought to have lived in cabins scattered along the river, and used the cave to store books and scientific equipment. The group of 40 monks—40 was believed to have a mystical significance—also erected a 40-square-foot tabernacle. The meeting space included a rudimentary observatory where monks practiced astronomy, thought to be the first observatory in the new world. Unfortunately all that remains is the small stone structure near the location where the tabernacle used to stand, the woods around and above it beautifully overgrown and wild. When the end of the world did not come as planned, Kelpius and the monks stayed in the Wissahickon, creating art and music, studying the skies, and helping the community around them when they could. The group mostly disbanded after Kelpius’s death in 1708, though many stayed in the community as doctors and lawyers. One of the later members of the Society, Christopher Witt, painted the first oil painting in America, with Kelpius as his subject. The painting is currently housed at the Historical Society of Pennsylvania. Until the 1940s, the structure dubbed Cave of Kelpius had a fireplace and chimney, which were removed due to vandalism, but do hint at its having been more than a springhouse. The cave’s true identity has been debated for many years. It’s marked today by a granite monolith placed outside the entrance in 1961 by the Rosicrucians (meaning “rose” and “cross”), a worldwide mystical brotherhood that claims to have secret wisdom dating to ancient Egypt, and considers Kelpius the original American Rosicrucian. Today, you’ll find the enigmatic structure located on the trails near the southern end of the 1,800-acre Wissahickon Valley Park, a section of Fairmount Park in Northwest Philadelphia. Know Before You Go

From Philadelphia, take Ridge Avenue to the beginning of the Wissahickon Bike Trail, and turn right onto the trail. Follow the trail into the woods (by foot or bike), alongside Lincoln Drive for almost a mile, then turn left. Alternatively, take Ridge Avenue to Lauriston Street and turn right, then turn left onto Righter Street, right onto Rock Street, continue onto Quentin Street, then turn right to get to Daisy Field, which is near the cave. Be warned that it's not easy to find - most stumble upon it by accident. Article by:

Long ago, a group of forty German Pietists lived in the beautiful forest of Colonial Philadelphia, along the Wissahickon Creek which flows in a lush, deep valley. The valley was often used by the Native American tribe of the Lenni Lenape for hunting and fishing. The leader of these forty religious men, was Johannes Kelpius. He was born in Transylvania and was highly educated at European colleges and then became a respected religious leader. He referred to the book of Revelations in the Bible, believing the end of days was soon coming by the year of 1700. The Monks traveled to the 'New World' for religious freedom, to pursue occult philosophies and do various strange practices that were not allowed in Europe. Such as alchemy, astrology and even divination to see the future. These pioneering Monks also created lots of incredible music for their worship services, written down in their hymnal books that still exist. Their music was unique and also incorporated the first pipe organ that they brought with them, along with other instruments for musical performances!

They awaited the arrival of this enchanted woman, the angel of God, believing she would guide them into a new reality, in the virgin wilderness of early America. So the mystic Monks thus called themselves, "Society of the Woman in the Wilderness" Their home was a huge log Tabernacle and built it forty foot square in following their belief of sacred numerology. This building included the first obersavtory built in America upon the roof, complete with a telescope to watch the stars at night. They looked for signs of the Woman's eminent arrival, to usher in Armageddon, as written in the Bible. According to the preserved diary of Kelpius, a mysterious apparition of a magical woman actually did appear to them on three separate occasions! However, she quickly vanished leaving the brotherhood confused and disillusioned....
