This is Durnstein Castle, perched on a precipice high above the Danube River in Austria some 60 miles upriver from Vienna. Built in the early 1100s, here is where King of England Richard the Lionheart was imprisoned, having been captured by his enemy Leopold V of Austria on his return from the Third Crusade in the Holy Land.

The story is well known of how Richard’s brother John had usurped the throne and impeded paying Richard’s ransom – and the legend of Robin Hood raising the money pilfering it from thieving nobles. The ransom was finally paid in 1194, with Richard returning to be crowned King of England once again. The castle fell into disrepair, uninhabitable since the late 1600s. It is an eerie journey back into history to explore it today. (Glimpses of Our Breathtaking World #197 photo ©Jack Wheeler)

Rising 600 feet above the jungles of central Ceylon (Sri Lanka) is a gigantic rock column revered for millennia as Sigiriya – Lion Rock from Sanskrit. It’s flat on top, used over centuries as a Buddhist monastery and a fortress by kings. In 480, King Kashyapa had the image of a lion carved into the rock as the entrance gate to his fortress-palace on top. All that’s left are the lion’s paws that you see.

It was a risky climb via stone stairs carved into the rock getting to the top. Today there’s a much safer wooden staircase. It’s a pilgrimage site for Sri Lankans where they get to celebrate their history and enjoy the gorgeous view on top. It’s a marvelous experience for you to participate in.

The Antarctic island of South Georgia is home to a million King penguins, plus countless fur seals, gigantic elephant seals, staggering numbers of seabirds such as albatrosses, amidst a backdrop of towering mountains with massive glaciers spilling off them.

Nothing can prepare you for the incomprehensible size of the penguin rookeries here, densely packed as far as the eye can see (all those white dots on the hills behind are penguins). Nor for the size of bull elephant seals weighing up to 8,000 pounds, especially when they rise up and crash their chests against each other in mating challenges emitting deafening bellows. Nor being surrounded by a thousand fur seals unafraid of you. The density of wildlife combined with the magnificent beauty of the island is completely overwhelming.

Here also is the abandoned whaling station of Grytviken where the heroic explorer Ernest Shackleton is buried. You can only get here by expedition cruise ship. South Georgia is one of the great experiences on our planet. (Glimpses of Our Breathtaking World #96 photo ©Jack Wheeler)

Go down to the Atlantic coast beach of Mauritania’s capital Nouakchott at sunset, and you’ll see a very unusual fish market. A fishing boat laden with the day’s catch is ready to come ashore, but the crew is afraid the wind and surf may capsize the boat as they do, losing their catch in the process.

So they float just outside the surf line so buyers with boxes and baskets can wade out to buy the fish right off the boat, and wade back. Only when the boat is empty will the crew attempt to beach it. Just one of this West African country’s intriguing sights.

Many centuries ago, a tiger was plaguing the Naxi people who live in the mountains where the Yangtse River cascades off the plateau of Tibet. He was eating the goats the Naxi needed to feed themselves. So Naxi hunters chased the tiger into a deep narrow gorge of the Yangtse where they were sure they had him trapped. Suddenly, the tiger sprang onto a large rock in the center of the raging river and from there leapt to the other side and escaped, never to be seen again.

Ever since, where this took place has been known as Tiger Leaping Gorge. Here you see Tiger Leaping Rock. I was first here in July 2002 on our overland expedition across eastern Tibet. Last time 2015. Maybe again? (Glimpses of Our Breathtaking World #141 Photo ©Jack Wheeler)

Between Sicily and Tunisia in the Mediterranean lies a secret hideaway of Europe’s rich and famous – the small Italian island of Pantelleria. Peaceful and quiet, the opposite of glitzy places like Ibiza, wealthy elite retreat here in luxurious yet very understated villas to get away from it all. It helps that the shoreline is all volcanic rock cliffs, which dissuades hordes of African “migrants” attempted to claim “asylum” in the EU welfare state by landing here.

The most beautiful spot on Pantelleria is this volcano crater lake known as “The Mirror of Venus” – of such magic color that, the legend goes, the goddess Venus would admire herself in its reflection. Come here for a tranquil escape of your own. (Glimpses of Our Breathtaking World #164 photo ©Jack Wheeler)

The Ancient Greeks began settling in the Mediterranean’s largest island around 750 BC. They called it Sikelia, after the Sikani and Sicel tribes that lived there. They flourished, building numerous cities, all with temples to their Olympian gods. The city of Akragas – now called Agrigento on the south coast – grew to a population of 200,000 by the 500s. It was here that the Greeks built the most outstanding examples of monumental Greek architecture that still exist today.

Along a ridge outside the city, they erected temples to Zeus, Hera, Heracles (Hercules) and many others. The one you see here the Romans called the Temple of Concordia (harmony), for by the time they showed up in the 200s, the Greek name was lost. In the foreground lies a remnant of a bronze statue to one of the Greek gods – perhaps Apollo. The glory that was Greece has been gone with winds of millennia. It can be a very emotional experience to be here.(Glimpses of Our Breathtaking World #248 photo ©Jack Wheeler)
