Trujillo, Peru, Main Square,
Plaza de Armas

Trujillo is a city in coastal northwestern Peru and the capital of La Libertad Region. It is located on the banks of the Moche River, near its mouth at the Pacific Ocean, in the Valley of Moche. This was a site of the great prehistoric Moche and Chimu cultures
before the Inca conquest expansion. It
is the centre of the second most
populous metropolitan area of Peru.

Trujillo is close to two major archeological sites of pre-Columbian monuments: Chan Chan, the largest adobe city in the ancient world, designated a World Heritage Site by UNESCO in 1986; and the temples of the Sun and Moon (the largest adobe pyramid in Peru). Source:

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.
