Buckingham Palace is the 775 room residence of Britain's sovereigns (since 1837).
The Queen's Guard stand sentry in front of both this palace and St. James Place. When the Queen is in residence, there are four guards, but when she is away from Buckingham Palace, there are only two.
You always know the Queen is in residence by the flying of her royal standard. If this flag is flying, the Queen is inside.
On the border between Tanzania and Kenya, just south of the Equator, is the tallest mountain in Africa: Mount Kilimanjaro.
Nobody actually knows for sure where the name came from. There are several theories, but each is flawed for various reasons. The name antedates the record of its etymology. It was known about anciently by traders and historians from as far away as China: there are records of a giant mountain inland from Zanzibar, but so far as anyone knows, it wasn't really explored until the mid 19th century.
It's actually three volcanos, two of which are extinct. The remaining peak, the highest, though, is dormant with its magma 1,310 feet below the surface.
The peak of Kilimanjaro is a "sky island" - a piece of land so high up as to be isolated from its surrounding land. It's actually considered an "easy" climb, but because it is so high up, many people get altitude sickness and some have even died from it. If you want to make this climb, take it easy, take it slow, and don't forget to take lots of pictures!
San Benedicto is the largest of the island group. It was first called Santo Tomas, but that changed with explorers "re" discovering it.
San Benedicto
Socorro was originally called Innocentes. A second explorer "rediscovered" it and named it Isla Anublada (Cloudy Island), and then it was rediscovered again and renamed to Isla Socorro (after "Virgen del Perpetuo Socorro).
Clarion is semiarid to arid throughout, but like all the islands in this archipelago, has a vibrant underwater profile. The Clarion Angelfish (a juvenile one in the picture - they lose the blue striping when the mature) is endemic to the region. Clarion was originally named Santa Rosa, but was rechristened after the name of the vessel commanded by the explorer that discovered it.
Finally there is Roca Partida - broken rock. No name change for this volcanic chunk poking up out of the sea, no vegetation, the occasional shorebird, and only 3.5 acres in area.
Of course, there's more to Oman than gorgeous sunset beaches. Oman is about the size of New Mexico, which means there's some interior to this Sultanate. 
It stretches 5,500 miles long.
If you were to draw a line between Los Angeles & New York, it would only be half that size (2,451 miles as the crow flies). That's a long wall.
It was begun sometime around the 8th century BC and sections continued to be built, added to, and rebuilt up through the 15th century (AD).
As a symbol of China and a world heritage site, efforts are being made to preserve the wall which has fallen victim to centuries of desertifation, sand storms, erosion, and in our modern enlightened society, vandalism.
There's a lot of work to be done, but even if I never get to stroll down it, I'd like to think it is there and will be there forever.
In Eastern Greenland, you will find the town of the "Big House Dwellers," or "Ittoqqortoormiit" in the Eastern Greenlandic dialect.
There is a surprising variety of life to be found in this icy climate.
Musk Ox, Polar Bear, Stoat, and Black-Headed Gull
It is a good place to see the Aurora Borealis.
Looks a little cold to me, though.
In the northeast corner of France lies the Champagne region, in which you will find the town of Reims.
Reims was settled around 80 BC, lasting through the Roman Conquest, Civil War, and two world wars. It has many sights worth seeing, including Roman ruins, a range of cathedrals and churches, and the place where the Wehrmacht surrendered (unconditionally) to Eisenhower and the Allies ending World War II.
Truly a region steeped in history.
