These beautiful travertine terraces in northern Iran are an incredible natural phenomenon that has evolved over thousands of years. Travertine is a type of limestone that is formed from calcium deposits in flowing water, and in this case, it is two hot springs with different mineral properties. The abnormal reddish color of the roof is caused by the high content of iron oxide in a fountain.

In recent years, efforts have been made to preserve the site due to the increase in tourism activity. These locations are one of the strangest places on Earth, providing visitors with a glimpse of one of the most bizarre attractions on the planet.
Megalithic stone jars are scattered throughout Jiang Khoang Province in Laos in groups ranging from one to one hundred. A working theory is that huge cylindrical jars were used in ancient funeral ceremonies, although according to local legend the jars were used to make rice wine for giants.

Northern Laos was the subject of a massive air bombardment by the United States, and it has been relatively recently cleared of some areas and declared safe for visitors.
One of the strangest places in the world is Cat Island in Japan. It is a short ferry ride from the east coast of Japan. There are about a hundred people on the island known as Tashirojima, but there are even more cats.

Cats were mainly welcomed because the island produced silk, and the rats, which were a threat to silkworms, were kept away by the cats. The fishermen also thought that cats bring good luck. There is even a cat temple and cat-shaped cabins for tourists. Dogs are not allowed to move.
Recently, Cat Island has become a popular place for tourists who love cats. People work to keep cats healthy, with volunteers and groups providing food and medical care.
