El Templo del Sol - Machu Pichu

Name : El Templo del Sol (or) Temple Of Sun

Location : Machu Pichu, Peru

Description : The Sun Temple was a ceremonial temple to honor the Inca god of Sun. The Temple is the only round building in the complex. A very sacred structure, only the emperor and high priests would have been allowed inside.

In the center of the temple you can see a sacrificial stone which was used in worship. There are two windows in the temple. On the two solstices of the year, at sunrise, the sun shines directly into the Sun Temple through these two windows and forms a rectangle on the sacrificial stone.

The winter solstice was on June 21st and people gather to see this rare occurrence.
