Having created one in 3D for my Memory Palace I am more familiar with the structure of these stepwells. They look complex, Escher-like and surreal but actually they are fairly simple and beautiful solution to the problem of getting water from down there to up here.
The Architectural Elements series focuses on the 'bits' of architecture to hone in our skills and sharpen our brushes. Short and succint classes, these are the building blocks of buildings.
Please note that these, like the rest of the Masterclass series, are one-off classes and will not be repeated.
