Successive Golden Rectangles dividing a Golden Rectangle into squares (logarithmic spiral known as the golden spiral).


Ica, Peru, Main Square, Plaza de Armas
The city of Ica is the capital of the Ica Region in southern Peru. While the area was long inhabited by varying cultures of indigenous peoples, the Spanish conquistador Gerónimo Luis de Cabrera claimed its founding in 1563. As of 2005, it had an estimated population of over 219,856. The city suffered extensive damage and loss of life during the 2007 Peru earthquake. Source: Wikipedia: Ica.

Golden rectangle
A golden rectangle is a rectangle whose side lengths are in the golden ratio, one-to-phi, that is, approximately 1:1.618. A distinctive feature of this shape is that when a square section is removed, the remainder is another golden rectangle, that is, with the same proportions as the first. Square removal can be repeated infinitely, which leads to an approximation of the golden or Fibonacci spiral.
