Michigan Triangle

The Bermuda triangle is one of many that is shrouded with intrigue.

The Michigan Triangle, which is located in the middle of Lake Michigan has also been the point of multiple disappearances and bizarre events.

One of the most mysterious incidents was that of the Rosa Belle ship in 1921.

Eleven people on the vessel disappeared and the boat was found overturned and floating in the lake.

It appeared as though the ship had been damaged in a collision, but no remains of another boat were found and no accidents were reported.

And the mystery is not just restricted to those on the water, as Northwest Orient Airlines Flight 2501 disappeared in the triangle in 1950.

The plane was carrying 55 passengers and three crew and was one of the deadliest commercial airliner accidents of the time.

The cause of the crash was never determined, as the plane’s wreckage was never found, although human body fragments and light debris were found floating on the lake surface.

Mystery of Hollinwell

The Hollinwell incident is one of the strangest to happen in Great Britain.

Back in July 1980 nearly 300 kids in a field near Kirkby-in-Ashfield, Nottinghamshire, who were competing in a brass band competition, suddenly became extremely ill.

Reports said the children were hit by vomiting, runny noses and sore eyes.

The cause of the symptoms were never determined, but health authorities at the time suggested it was a result of mass hysteria.

Rendlesham forest incident

In 1980 a US military personnel claimed to have seen an alien spacecraft at Rendlesham Forest in Suffolk.

Unexplained lights were seen on two nights before New Year, which sent livestock in the area in to a “frenzy.”

When they reached the point where the flying objects appeared to have made contact with the ground, they only found burn marks on the ground.

Charles Halt, who was a colonel in the US Air Force, reported the incident to the Ministry of Defence.

Scientists tried to explain the sighting saying it could have been bright stars or flashes from a lighthouse.

Some claim the sighting was a hoax, but Charles later accused American and British officials of conspiring to cover up the incident.

Overtoun Bridge

Nestled between rolling hills and meandering streams lies a 150-year-old castle known as Overtoun House.

The Gothic building spans a narrow river on the grounds of a 19th-century manor and is a favourite spot for dog walkers.

But there is something strange about the ancient bridge — 600 dogs have jumped from it, some to their deaths.

The gruesome goings-on at “Dog Suicide Bridge” have baffled owners as their beloved pets, seemingly out of nowhere, leap from it and fall 50ft to the rocky stream below.

Of the hundreds of dog deaths, all the animals are long-nosed breeds, such as retrievers. They jump mostly from between the same two parapets and in clear weather.

Some suggest paranormal activity is to blame — locals say it is the ghost of the depressed Lady Overtoun, who died in 1931, passing her sadness on to the animals.

The more scientific view is that they can smell something below the bridge, such as the strong scent of mink.

The Dighton Rock

A 40-ton boulder next to the Taunton River in Massachusetts has baffled scholars for over 300 years.

The rock is covered in puzzling petroglyphs, which are rock carvings with pictures.

Many have attempted to decode the writing on the boulder, since it was first reported in 1680.

Some speculate that the carvings are from Native American origins, and some think it was the work of the Portuguese, Chinese, or even the ancient Phoenicians.

Who put Bella in the Wych Elm?

In 1943, four boys were playing in the Hagley Woods, Worcestershire when they stumbled across the grisly remains of a woman inside the hollow wych elm.

Even though there were signs of struggle on the body, they believe the estimated-35-year-old was murdered by asphyxiation, when taffeta was stuffed into her mouth.

Months after the crime, graffiti began appearing in the region, which posed the question: “Who put Bella down the wych elm?”

Press reports in 1953 from the Wolverhampton Express and Star explore the idea that the victim could have been targeted by a German spy ring.

Another theory that’s passed through generations is that ‘Bella’ was killed for being involved in black magic.

Just like in other witch-related cases, the bones of the victim were scattered around in a ritualistic way.

Decades on, the mystery is still as fascinating and chilling as ever, with many calling on the police to re-consider the evidence or to carry out some DNA tests.
