Rhuidean was built based on memories of the Age of Legends.
Charn made his way down the side of the wide, crowded street beneath the spreading chora trees, their trefoil leaves spreading peace and contentment in the shadows of silvery buildings that touched the sky... above the blue and silver domes of the Collam Daan.

Now is "Randland" earth? Yes
Is our earth a future or past turn of the wheel?
Both. The characters in the books are the source of many of our myths and legends and we are the source of many of theirs. You can look two ways along a wheel. - Theoryland
Did Jordan base his writing on real world things? Yes
From a large interview found here (4) by team Jordan. FYI Team Jordan is Robert Jordan and his editors, and finally Brandon Sanderson. Sanderson and the team of editors worked together to finish the final 3 books, as well as release the wheel of time compendium that came out recently.
I've recently been in a course in Restoration Literature, and in the historical studies there, I noted that there seem to be connections between Cairhien and London around the time of the mid-to-early 1600s... and I just was sort of wondering if there is actually any of historical London in Cairhien, and if there is, is there any more anywhere else in the major cities?
Yes, yes. One thing you have to remember about Jim is he never did a single reference in any of his descriptions, whether it's a military uniform, a city, a character—everything seemed to draw from multiple sources. So yes, Cairhien was most likely in part based on London, but you look at the map of it, and you can see it's very different as well.
Yeah, another interesting point: anyone remember what the name Cairhien means in the Old Tongue?
Hill of the Golden Dawn.
Hill of the Golden Dawn. The Order of the Golden Dawn was an occult society in London back before the beginning of the 20th Century.
This particular society was Kabbalistic, and their hierarchy is based on the Tree of Life. Many other parallels can be drawn.
Yeah, that's right. I'd forgotten that.
Which I just bring out as, you know, yet another thing that Jim latched on to and threw into the mix.
Most people think 'the hill of the golden dawn' is like, 'Oh, the land of the rising sun!' which would be Japan, because there's a heavy Japanese influence in just the style of the buildings and things like that seem very Japanese.
Sure. And the Sun King of France.
Yeah. It's kind of like he just pulled everything that was related to the sun and just kind of melded it together to make Cairhien.
Looking at how Jordan took real world cities, objects, and history and incorporated it into his storys, its pretty clear the Age of Legends was meant to remind us of modern cities, skyscrapers made of steel and glass, or perhaps power strengthened stone and glass. So Rhuidean built by people who had access to memories and stories of the age of legends would also bare a resemblance to a more real world modern city.
