Sullana, Peru, Main Square, Plaza de Armas
Sullana is the name of the capital of the Sullana Province, in the north-western coastal plains of Peru on the Chira valley.

The Chira valley has always been an important farming area. Before the Spanish Invasion, ethnic groups like the Tallanes, the Mochicas, the Chimú, and finally the Incas had settled here. This region was chosen by the Spaniards to found their first city in this part of the Americas, San Miguel de Tangarara, on July 15, 1532. Source: Wikipedia: Sullana.

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.
