Susami is home to the world's deepest underwater mailbox, a fascinating Japan fact. Susami is a popular fishing village in Wakayama Province. In 2002, the town's deepest underwater mailbox was certified by Guinness World Records. Since 1999, the mailbox has gathered over 32,000 pieces of mail at a depth of 30 feet.

Folk dance is a significant aspect of Russian history and culture. One of the most popular styles of Russian folk dance is khorovod. People dance in a circle while holding hands in this kind of dance. Folk dances are performed by Russians during festivals, marketplaces, and in the theatre. If you have the opportunity to visit Russia, make sure to attend a Russian folk dance performance to learn more about Russian culture and traditions.

Did you know that because Russia is so large, it has 11 separate time zones? Despite having 11 time zones, Russia is not the country with the most time zones. Because of all the little islands that make up France, it has the most time zones. While Russia does not have the most time zones, it does have a large number of them. If you opt to travel across Russia, you may suffer from jet lag before ever leaving the country!

Did you know that Russia has the world's longest railway? The Trans-Siberian Railway runs 5,772 kilometres from Moscow to Vladivostock. The Trans-Siberian Railway makes it simple to travel throughout Russia by rail at your own pace. Depending on your budget and desired experience, you can ride in a first-class cabin or third-class seats. If you want to travel China or Mongolia, the Trans-Siberian Railway links to those nations as well.

Another shocking fact about Russia is that it has 12 active volcanoes! Because of its convenient position, Kamchatka is one of the most visited of these volcanoes. If you enjoy nature and stunning scenery, you should go to Kamchatka. This active volcano is home to approximately 1,000 plant species. Brown bears, lambs, and wolves also live there. You may explore Kamchatka on your own or as part of a guided excursion. If you are not fluent in Russian, an organised trip is the better alternative.

It's an earthquake hazard area. Although several earthquakes have been reported in and around the Black Sea, the greatest recorded magnitude was 7.2 in the 1901 Black Sea earthquake (also known as the Balchik earthquake in Bulgaria). The mainshock triggered a 1-16 foot tsunami, wreaking havoc on the Romanian and Bulgarian shores. The aftershocks continued four years longer.

Some of the rocks date back more than 540 million years. The rocks along the Russian Platform date back to the Precambrian epoch, the earth's first aeon. This epoch spanned from the birth of the solar system 4.6 billion years ago through the emergence of the first multicellular creatures. To put it into perspective, the ancient rocks in the Black Sea existed for about 300 years before dinosaurs were on the scene.

It is the biggest inland body of water in the world. The Black Sea has a total area of 163,000 square miles, which is larger than the whole state of California. The Black Sea, however, differs from most other inland bodies of water in that it is also classified as a marginal sea.

It is also the biggest meromictic basin in the world. A meromictic lake contains water strata that do not mix together. Regular holomictic lakes, on the other hand, have at least one period every year when the surface and deep waters mix. Although meromictic lakes may be found all over the world, they are extremely uncommon. The proportion of meromictic lakes to holomictic lakes is around one to 1,000.

Lower levels are almost biologically dead. One of the most intriguing aspects of the Black Sea is its absence of oxygen, which is required for life. Because oxygen can only be dissolved in the sea's top layers, anything below 230-330 feet in the centre and 330-500 feet at the edge is effectively a dead zone. Only particular bacteria can thrive in these areas, which account for more than 90% of the deeper water.

What you conceive of as a wonderful city today has a lengthy and little-known past. Some long-held hypotheses hold that London was founded by Romans around the year 50 AD. The origin of its name is likewise a mystery. London was known by several names throughout history, including Londonium, Ludenwic, and Ludenberg. The most widely accepted explanation is that the name London is derived from the old Celtic word "Londinous," which meaning "brave."

London is a significant cultural and historical centre, and museums could not be overlooked in this regard. If you get the opportunity to visit this great city, you will undoubtedly miss out on a lot if you do not stop by one of them. Among these are the British Museum, the National Gallery, the Imperial War Museum, the British Library, and the Wallace Collection.

USA's present 50-star flag was created by 17-year-old Robert Heff as part of a high school project. It was 1958, and there were only 48 states at the moment, but Heft had a feeling Hawaii and Alaska would get statehood shortly. His teacher gave him a B- but later raised the mark to an A after Heft submitted his design to the White House, resulting in a call from President Eisenhower announcing that it had been chosen as the official U.S. flag.

Everyone knows Lake Superior is vast (it's not called one of the Great Lakes for nothing), but few people realise precisely how big it is. Lake Superior is not only the world's biggest freshwater lake, but it also carries three quadrillion gallons of water. That's enough liquid to submerge North and South America under a foot of water. It's no surprise that Lake Superior has seen so many shipwrecks.

Because the moon lacks an atmosphere, there is no wind or water to erode or wash away the Apollo astronauts' imprint. That implies their footprints, roverprints, spacecraft prints, and waste stuff will be maintained for a very long period on the moon. They will not, however, remain there indefinitely. The moon is still a changing environment. It is regularly pummelling with "micrometeorites," which indicates that erosion is still occurring on the moon, although slowly.

Curious about how Batman manages to achieve what he does? Do you want to know everything there is to know about the Dark Knight? The Science of Batman is a genuine subject offered at the University of Victoria in Canada. "The great range of flexibility of the human body explored via the life of the Caped Crusader," according to the course description.

You may have be aware that Valentine's Day was named after its patron saint, St. Valentine — but there is some debate about which St. Valentine the celebration truly commemorates. According to History.com, at least two persons called Valentine may have inspired the festival, one of whom was a priest in third-century Rome. According to legend, this Valentine disobeyed Emperor Claudius II's marriage ban (he believed it distracted young troops), illegally married couples in the spirit of love until he was apprehended and put to death.

Italy was a dictatorship until 1945, while having a royal dynasty until 1946. Following WWII, the country decided to become a republic, and King Umberto II governed briefly from May 9 to June 12, 1946. He spent the rest of his days in exile in Portugal. In Italy, he is regarded as "the May King," a reference to his exceptionally brief rule.

Taman Negara is the world's oldest tropical rainforest, believed to be more than 130 million years old. Taman Negara translates to "national park" in Malay. To enter the park, you must obtain special authorization from the government, but it is definitely worth it if you have the time. Rare creatures like as the Malayan tiger, crab-eating macaques, Sumatran rhinos, and even the Asian elephant call this jungle home.

The endangered European bison, sometimes known as the wisent, is Europe's biggest land mammal, weighing more than 600kg on average. They may be found roaming the 150,000 hectares of Poland's Biaowiea Primeval Forest — Europe's remaining primaeval forest, which originally stretched across the continent thousands of years ago.

One of our favourite amusing facts about Poland is that it is home to the world's first upside down house. The topsy-turvy wooden home was erected upside down in a forest and appears to be something out of a storybook. Visitors must enter the home through the attic windows and may walk around the furnished interior, which is evocative of Communist Poland in the 1970s, to symbolise how Communist control turned life in Poland upside down. Hundreds of interested visitors have visited the home since its unveiling in 2007, and it is located in the little Polish town of Szymbark, which has a population of roughly 500 people.

Have you ever visited a salt mine? When you travel to Poland with Trafalgar, we will take you to the 800-year-old Wieliczka Salt Mine, one of the world's oldest. It's known as the Underneath Salt Cathedral of Poland, and when you go 135 metres (440 feet) underground with your guide, you'll witness chambers, sculptures, salt chandeliers, and an entire church sculpted from rock salt. The UNESCO World Heritage Site has been producing salt continuously since the 13th century until 2007, and the history and unique carvings of this salt mine will leave you speechless.

Algeria is the continent's biggest country, spanning more than 2 million square kilometres and borders Mali, Niger, Libya, Tunisia, Morocco, and Mauritania. This places it above Libya, Sudan, and the Democratic Republic of the Congo, and it is about five times the size of Spain.
