Shell Grotto

Underground caves lined with millions of shells, and no one knows who built them.

The Shell Grotto in Margate, Kent, England, stands as one of history’s most baffling mysteries.

Discovered in 1835, this hidden passageway is adorned with over 4.6 million meticulously arranged shells, forming elaborate mosaics that cover every inch of its walls and ceilings.

The designs are precise and intricate, depicting symbols, patterns and figures whose meanings remain shrouded in mystery.

What makes the grotto so compelling is that no one knows who created it, when, or why.

Some speculate it dates back to ancient times, possibly as far as the Roman or Phoenician period, while others believe it was constructed in the medieval era or even the 18th or 19th century by an eccentric individual.

Was it a secret temple, a meeting place for a hidden society, or a mysterious art project?

Theories are abundant, but definitive answers are nonexistent.

The Shell Grotto is more than just a stunning piece of craftsmanship. It’s a riddle that continues to confound experts and captivate visitors from around the world.

X-ray imaging, PET scans, CT scans, and MRIs are various imaging techniques that are used to capture images of the inside of the body. 🩻

X-ray

— detects bone fractures, certain tumors and other abnormal masses, pneumonia, some types of injuries, calcifications, foreign objects, or dental problems.

MRA

— Magnetic Resonance Angiography uses a powerful magnetic field, radio frequency waves, and a computer to evaluate blood vessels and help identify abnormalities.

MRI

— Magnetic Resonance Imaging uses a magnetic field and radio waves to take pictures inside the body.

It is especially helpful to collect pictures of soft tissue such as organs and muscles that don't show up on x-ray examinations

PET scan

— Positron Emission Tomography may be used to evaluate organs and/or tissues for the presence of disease or other conditions.

PET may also be used to evaluate the function of organs, such as the heart or brain.

The most common use of PET is in the detection of cancer and the evaluation of cancer treatment.

CT scan

— Computed Tomography is used to identify disease or injury within various regions of the body.

For example, CT has become a useful screening tool for detecting possible tumors or lesions within the abdomen.

A CT scan of the heart may be ordered when various types of heart disease or abnormalities are suspected.
