As soon as you arrive in Cusco, you will visit the Sun Temple (QORIKANCHA), the ticket is 15 pesos (1 peso = 2RMB), which is a must-see attraction for group tours. There are many tourists in the Sun Temple, and the tour guide waved the small flag, but it was very quiet. Tourists used headphones to listen to the explanation. In the Inca era, Cusco was the capital of the Inca Empire and was considered the center of the world, and the temple of the sun was supreme. In the agricultural era, people prayed that the sun god would never disappear. There are also stone relics in Machu Picchu that are meant to hold the sun. So far, every June on the winter solstice in South America, a grand ritual of worship is held. Cusco's temple is now a site, with only some of the ruins of the exterior walls. The stone walls we see are made of irregular but large smooth flat boulders like blocks, with the stone bumps tightly occluded, without a single crack, showing the design, wisdom and skill of the craftsmen of the Inca era. Historically, the Inca-era sun shrine, boulder buildings, outer gold plaques wrapped in the moon, stars, rainbows and thunder gods, in addition to the worship of the sun god, are known as the Golden Temple or Golden Garden. The Spanish colonists invaded, the gold foil was looted, and the temple was transformed into a monastery. Now it can see some replicas of the old furnishings, many religious paintings, sculptures, artifacts, etc. The garden outside the temple is full of mystery, which makes people admire and admire the Inca culture.
