This is Mount Nemrut in Turkey, one of the strangest ancient ruins in the world.
It's a colossal, 2,000 year old burial mound on top of a mountain, surrounded by huge stone heads.
Who built it? A king who wanted to become a god...
First, where is Mount Nemrut?
It's in the Taurus Mountains, a range in south-eastern Turkey. And, rising to more than 2,000 metres, it's one of the tallest mountains in the region.
It was part of the ancient Kingdom of Commagene, a small state that fought both with and against the Roman Republic, and eventually became part of the Roman Empire.
The tomb-temple at Mount Nemrut was built in 62 BC, when Commagene was an independent kingdom.
In Medieval Europe landscape painting wasn't a genre of its own, and it hardly featured in art at all.
Notice how the background of this 11th century mural indicates the landscape merely by the generic sketch of a castle and an isolated, highly stylised tree:
This changed in the 14th century with Giotto, a revolutionary painter from Florence.
He introduced proper landscapes into his paintings: rocks, trees, flowers, and skies.
But Giotto's version of nature remains highly stylised; this is not a "realistic" landscape.
This is the American Radiator Building, a 101 year old black and gold skyscraper that's half Gothic, half Art Deco.
It's famous, but not as famous as it should be — so here's a brief history of one of the world's coolest skyscrapers...
In 1923 the American Radiator Company wanted to build a new office in New York.
This was the Golden Age of Skyscrapers: the Woolworth Building was ten years old, and the Empire State and Chrysler were less than a decade away.
So it was going to be a skyscraper... but what sort?
Enter Raymond Hood, an architect who had just won the competition to design Chicago's Tribune Tower.
Even though it hadn't yet been completed, his Neo-Gothic design was so well-received that the American Radiator Company wanted him to design their new skyscraper.
When you hear the word "Brutalism" what comes to mind?
Maybe something like this: an uninspiring line of highrises, the sort people tend to call boring, generic, or even oppressive.
But that isn't real Brutalism — and it never has been.
Brutalism has become a byword for any modern building made primarily of concrete.
But that would be like saying Gothic Architecture is anything built from stone, or that Islamic Architecture is anything with ceramic tiles for decoration.
