Philip Callahan and The Round Towers

Philip Callahan and The Round Towers

Philip Callahan has always been a keen hiker and after World War II he decided to take the scenic route home from Japan by hiking across Asia and the Middle East.

Therefore, it’s no surprise he is very familiar with the Northern Hemisphere night sky.

Northern Sky Map

However, what is surprising is that Philip Callahan believes a map of the Irish Round Towers [when enhanced with a few connecting lines] provides a rough star map of the Northern Hemisphere night sky around the December solstice.

Towers and Stars

Philip Callahan is also interested in paramagnetism and he has demonstrated that most of the Irish Round Towers [except for those built of limestone] will be susceptible to paramagnetism.

Irish Round Towers - Materials

To test his hypothesis be built a model Round Tower from card which he coated with crushed grains of red clay flower pot.

Although the clay granules alone did not stick to a 1,000 gauss magnet he found the Round Tower [coated with clay granules] was attracted to the magnet.

Suspended Round Tower

In another experiment using a 10 centimetre high Round Tower made from sandpaper he found “the power meter went up from 6 DB of energy to 9 DB of energy” when the Round Tower model was exposed to radio energy of three centimetre wavelength.

Overall, Philip Callahan demonstrated that his model Round Towers functioned as [both] Magnetic Antenna and Radio Wave Guides.

Based upon these results he determined, for example, the Devenish Round Tower which is 25 metres high would resonate with the 14.6 metre wavelengths coming from the night sky that were discovered by Karl Jansky in 1932.

Karl Guthe Jansky (October 22, 1905 – February 14, 1950) was an American physicist and radio engineer who in August 1931 first discovered radio waves emanating from the Milky Way.

He is considered one of the founding figures of radio astronomy.

An intriguing property displayed by detectors of radio signals is that they serve as rectifiers which covert alternating current [AC] to direct current [DC].

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.

The process is known as rectification.

Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves, copper and selenium oxide rectifiers, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches.

Early radio receivers, called crystal radios, used a “cat’s whisker” of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or “crystal detector”.

As noted, detectors of radio signals serve as rectifiers.

Because of the alternating nature of the input AC sine wave, the process of rectification alone produces a DC current that, though unidirectional, consists of pulses of current.

Therefore, it is hardly surprising that Philip Callahan believes that the Round Towers of Ireland “have not only the properties of a DC rectifier, but also the ability to detect and store incoming cosmic electromagnetic/magnetic energy, thanks to their dielectric properties.”

A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field.

When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization.

Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction.

This creates an internal electric field that reduces the overall field within the dielectric itself.

If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.

The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials.

These observations lead Philip Callahan to speculate that the high doors found in the Round Towers of Ireland enabled the builders to [literally] fine tune the design of these Magnetic Antenna [aka Radio Wave Guides] by adjusting the amount of dirt that was used to fill the bases of the towers.

Furthermore, Philip Callahan believes the large Round Towers of Ireland provide large scale benefits for agriculture just as the small scale round towers have been demonstrated to be beneficial for potted plants.

Callahan s breakthrough came quite suddenly and totally unexpectedly.

‘I was just admiring how clever the builders were to make a tower that had a very slight taper of three degrees.

Then it dawned on me how similar these towers looked to certain insect antennae. It was a complete revelation.’

Potting experiment

The only differences were the presence of the tower in one and corresponding reduction in volume of potting mix due to the volume of tower base inserted in the mix.

Stone Antenna

Philip Callahan highlights that the Round Towers of Ireland share their “hollow resonant stone tower” design with [both] Pagodas and the King’s Chamber in the Great Pyramid of Giza [which he believes was an antigravity structure for levitating the priests].

In my later readings on the pyramids of Egypt, I was surprised to lean that of the 30 or so different Egyptian pyramids, not a single mummy had ever been taken from inside a chamber.

Lots of mummies have been found, but in most cases, they were buried in underground chambers around or under the pyramids and not inside of them.

I am firmly convinced that the pyramids, both Egyptian and Central American, were huge antigravity structures for levitating the priests.

The pyramid acted like a huge “enlarger-type” condensing lens which concentrated the cosmic energy into the hollow resonant stone tower, which in turn was filled with the IR-paramagnetic, organic breath of chanting priests.

The Great Pyramid of Giza (also known as the Pyramid of Khufu or the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza pyramid complex bordering what is now El Giza.

Based on a mark in an interior chamber naming the work gang and a reference to fourth dynasty Egyptian Pharaoh Khufu, Egyptologists believe that the pyramid was built as a tomb over a 10 to 20-year period concluding around 2560 BC.

A pagoda is a tiered tower with multiple eaves, built in traditions originating in historic South Asia or with respect to those traditions, common to Nepal, India, China, Japan, Korea, Vietnam, Burma, Sri Lanka and other parts of Asia.

Some pagodas are used as Taoist houses of worship.

Most pagodas were built to have a religious function, most commonly Buddhist, and were often located in or near viharas.

The origin of the pagoda can be traced to the stupa (3rd century BCE).

The stupa, a dome shaped monument, was used as a commemorative monument associated with storing sacred relics.

The stupa emerged as a distinctive style of Newari architecture of Nepal and was adopted in Southeast and East Asia.

More remarkably, Philip Callahan sees the design of religious towers echoed in insect antennae.

As I drew my moth sensilla, I found myself saying, “Oh, there is a Siamese Chedi,” or “What do you know – a church steeple or pagoda,” or “That’s a corrugated spine – like the Red Tower of India.”

And the last 25 years I have seen the shape of every religious structure I ever visited in my walk in the sun, and each in exact miniature on the antenna of an insect.

Round-Tower Churches



The earliest mosques lacked minarets, and the call to prayer was performed elsewhere; hadiths relay that the Muslim community of Medina gave the call to prayer from the roof of the house of Muhammad, which doubled as a place for prayer.

Around 80 years after Muhammad’s death, the first known minarets appeared.

Islam is a monotheistic and Abrahamic religion articulated by the Qur’an, a religious text considered by its adherents to be the verbatim word of God (Allāh), and, for the vast majority of adherents, by the teachings and normative example (called the sunnah, composed of accounts called hadith) of Muhammad (c. 570–8 June 632 CE), considered by most of them to be the last prophet of God.

Star Towers

The rugged hinterlands of Western Sichuan province, between central China and the Tibetan Autonomous Region, an area known as the Tribal Corridor, were at one time dotted with thousands of lofty stone towers cunningly designed, skillfully constructed, remarkable in form and scale, and mysterious in origin.

Following Philip Callahan’s line of thinking it’s possible to argue that the levitating priests and the Round Towers have [both] been suffering from declining mojos because the Earth’s geomagnetic intensity has been declining for [at least] the last 2,000 years.

Earth’s magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth’s interior to where it meets the solar wind, a stream of charged particles emanating from the Sun.

Its magnitude at the Earth’s surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss).

At present, the overall geomagnetic field is becoming weaker; the present strong deterioration corresponds to a 10–15% decline over the last 150 years and has accelerated in the past several years; geomagnetic intensity has declined almost continuously from a maximum 35% above the modern value achieved approximately 2,000 years ago.’s_magnetic_field

Personally, I’m happy to drop the levitating priests for rising agricultural yields.

    Some very interesting thoughts from Louis Hissink:

    Philip Callahan is an entomologist, or studies insects, and has written a book for the layman that’s easy to read but he did write a clanger or two when he states that a dimagnetic material is slightly repelled by a magnetic field, and that a paramagnetic one is attracted to a magnetic field.

    Well worth reading….

    Have you heared about Michael Tellinger from South Africa and his research on ancient stone circles?
    Those are not towers but interesting anyway.

  3. Excellent book, with new insights. My own research into the round tower at Abernethy here in Scotland, shows that they attract certain form of energy from the burial grounds themselves. Very strange, but then, their culture was completely different to ours. My Youtube showing how they work is:

    David Cowan and Anne Silk – 2014

    Since the Stone Age our ancestors have tapped into the natural energies of the planet, building stone circles, standing stones, pyramids and temples in a highly evolved and brilliantly executed network of energy centers around the world.

    Thousands of years later, this ancient knowledge was brutally suppressed by the early Catholic church and ignored by science.

    But it still lingered on, kept by such secret societies as the Knights Templar and the Masons, who designed buildings and whole cities incorporating this esoteric knowledge, hidden in plan view.

    Here, Cowan brings together his own extensive work with the findings of other researchers, and reveals his discovery that the energy lines emanate from volcanic sources that spew out natural telluric energies in all directions, like the spokes of a wheel!

    Chapters include: Megalithic Engineering; Burial Grounds across Scotland; Following a Straight Ley Line to its Source; Saint Columba and Iona; The Royal Triangle of Great Britain; The Strange Behavior of Ley Lines; The Dance of the Dragon; Ley Lines in the USA; The Secret Knowledge of the Freemasons; Spirit Paths; The Occult Knowledge of the Nazis; How to Use Diving Rods; The Amazing Power of the Maze; more.

    Thanks, looked all over for the Hot Valley of the Eastern Queen now removed from accessability on the net. Ordered one of Phillip Callahan’s books. A megalithic researcher Gary Biltcliffe notes Etruscan connections to magnetic stone. Preservation of these will be your legacy. The internet is being reworked to have past discoveries omitted.
