There is an allure to round windows.
Even though they can be quite difficult to construct people still love them
and they even have a sort of soothing effect.
These first two were designed by Paolo Soleri,

This round, diamond square is at Cosanti near Scottsdale, Arizona.
For more see my post on Windows And Doors At Arcosanti And Cosanti.

Okay the round window above is not really a window
but a skylight in Zacatecas, Zacatecas, Mexico.
For more on skylights see my recent post:
We found this diamond in Silverton, Colorado.
