What are the most mysterious things or place on Earth that you know?

Surtsey, Iceland

When people try to convince you there's nothing new under the sun, direct them to the Icelandic island of Surtsey. Before 1963, it didn't exist. Then, an underwater volcano in the Westman Islands (Vestmannaeyjar) erupted, and when the activity settled down in 1967, what remained was an island where no island had been before.

2.Moeraki Boulders, New Zealand

Large spherical boulders -- some measuring 12 feet in circumference -- are scattered on Koekohe Beach on the east coast of New Zealand's South Island. They formed millions of years ago on the ancient sea floor, collecting and hardening sediment and minerals around a core such as a fossil or a shell similar to the way oysters form pearls.
They're not the world's only examples of what geologists call septarian concretions. You can also visit the Koutu Boulders near Hokianga Harbour on the northwestern coast of New Zealand's North Island, for example. Yet the Moeraki Boulders are some of the world's largest. The particulars of their origin and what caused the distinctive cracks inside them are still being studied.

3.Longyearbyen, Norway

From April 20 to August 23, the sun never sets over Svalbard, a Norwegian archipelago that lies north of Greenland in the Arctic Sea. The phenomenon plays havoc with everyone's body clocks. Is it noon? Is it midnight? After a day or two, it's hard to tell.

4.Pamukkale, Turkey

What appears to be a Doctor Zhivago-style snowy landscape in southwestern Turkey is actually the result of calcium carbonate deposits from 17 natural hot springs accumulating over thousands of years. Beginning in the late second century B.C., this area near present-day Denizli was a destination for those who sought the therapeutic benefits of the mineral-rich water whose temperature reaches upward of 100 degrees Fahrenheit.

Notch Hill church in Tappen, BC, Canada.
The light is from the train coming up behind it. Since this picture became popular on the internet and got a bit of press, they decided to restore the church.

San Zhi City, UFO Pods, Taiwan
Taiwan’s other-worldly “ruins of the future” are a set of pod-like buildings built in 1978 as a vacation resort. However, two years later the project collapsed due to financial problems and a number of deaths during construction. Deserted for a further 28 years, demolition finally began in 2008. Despite the original structures’ futuristic design, the land remains rooted in the past with current developers hoping once again to build a seaside retreat in the area.

7.Pripyat, Ukraine
Pripyat, a city of nearly 50,000, was totally abandoned after the nearby Chernobyl nuclear disaster in 1986. Due to radiation, it has been left untouched ever since the incident and will be for many thousands of years into the future. Nature now rules the city.

Hashima Island, Japan

Hashima island in Japan has a wide array of nicknames, including Battelship Island (for its shape) and Ghost Island. From the late 1800s to late 1900s, the island was populated because of the access it granted to undersea coal mines. However, as Japan gradually switched from coal to petroleum, the mines (and the buildings that sprung up around them to support their workers) closed down, leaving an isolated ghost town that reminds some of a ghostly concrete battleship.

Ryugyong Hotel – Pyongyang, North Korea
Unoccupied, unopened and unfinished, the 105-story shell of the Ryugyong Hotel is a scar on Pyongyang’s skyline and North Korea’s pride. Construction began in 1987 but stopped after five years due to a lack of funds. Once proudly emblazoned across North Korean stamps, this vacant hotel soon became airbrushed out of official photos. Despite nearly two decades of abandonment, construction resumed in 2008 but whether the hotel will ever be completed is open to debate.

Abandoned Military Hospital in Beelitz, Germany
A rotting carcass of deserted corridors and empty patient wards, this military hospital once housed German and Soviet soldiers but has been largely unused since the late 1990s. Derelict it may be but it has not been entirely abandoned; empty bottles and rubbish scattered on the ground hint at the disparate groups of opportunistic looters, weekend wanderers, curious travellers and inspired photographers who are drawn to the decayed aesthetic of this moribund site.

Six Flags Jazzland – New Orleans, Louisiana

Severely damaged by Hurricane Katrina, Six Flags Jazzland has been abandoned since. Several of the rides still stand, a testimony to the resilience of New Orleans. Several companies have plans to develop the park, but until then it will remain as the perfect setting for a horror movie.

Salto Hotel, Colombia
The Hotel De Salto opened in 1928 near Tequendema Falls in Colombia to serve tourists who came to marvel at the 157 meter-tall waterfall. It closed down in the early 90s after interest in the waterfall declined. In 2012, however, the site was turned into a museum.

Gulliver’s Travels Park – Kawaguchi, Japan
Constructed in the shadow of Mt Fuji, this theme park opened in 1997. Despite financial help from the Japanese government, it lasted only 10 years before being abandoned.

Underwater City in Shicheng, China
This incredible underwater city, trapped in time, is 1341 years old. Shicheng, or Lion City, is located in the Zhejiang province in eastern China. It was submerged in 1959 during the construction of the Xin’an River Hydropower Station. The water protects the city from wind and rain erosion, so it has remained sealed underwater in relatively good condition.
