The winter solstice indicates that the earth is in its farthest point from the sun. In the southern hemisphere it marks the beginning of the lengthening of the days. In pre-Colonial America, the native peoples of the Andean highlands depended on agriculture and their agricultural rituals were carried out to obtain the blessings of the gods, above all the Pachamama (Mother Earth) and Inti (Father Sun), to ensure an abundant harvest. The Quechuas and Aymara celebrated two annual festivities: the planting season and the harvest, coinciding with the summer and winter solstices. Some Amazonian tribes also celebrated the solstice, with other rituals and in a different manner, each according to their customs.

Winter Solstice or Willkakuti in Tiwanaku

Tiwanaku (or Tiahuanaco) is recognized by Andean scholars as one of the most important precursors to the Inca Empire, flourishing as the ritual and administrative capital of a major state power for approximately five hundred years. It is the most important site for this celebration. People flock from all over the world to watch the rays of the rising sun shine through the temple entrance on the eastern side of the complex. Locals celebrate the Amayran New Year by wearing colorful ceremonial clothing, drinking singani, chewing coca, sacrificing llamas and dancing until dawn. Tourists are welcome to join in the celebrations and can purchase local art from the artisan stalls set up to coincide with the event.

The Willkakuti or return of the sun is celebrated on June 21st in the pre-inca ruins of Tiwanaku. This ritual is known as the Aymara new year. The return of the sun symbolizes the reception of renewed cosmic energies and also the beginning of the new agriculture cycle.

The Andean-Amazonic New Year (Spanish: Ano Nuevo Andino Amazonico; Aymara: Willka Kuti or Return of the Sun) is a national holiday in Bolivia. It celebrates the winter solstice in the Southern Hemisphere and was declared a national holiday in Bolivia for the first time in 2010.

The Aymara New Year traditionally starts at the sunrise on the day of the solstice and is received by drums and quenas: the ancient sounds of Bolivian music. Each year more than thirty thousand people gather to witness this ritual.

The ceremony takes place in the esplanade of the semi-subterranean temple of Kalasaya, cradle of the oldest pre-Colombian civilization of America, the Tiwanakotas.

With arms extended to the sun, thousands of Bolivians welcome the arrival of the Aymara new year with ancestral rituals. In the mythical Gate to the Sun they wait for dawn to begin with the first rays of the sun the rituals of devotion to their gods.

Similar Celebrations

Similar celebrations to that of Tiwanaku take place in the city of Copacabana, province of Manco Kapac and the sector La Cumbre, with the coming of the Yungas (afro descendants) to La Paz.

Also in Pampa Aullagas, department of Oruro, the Fort of Samaipata in Santa Cruz with the "Yasitata Euasu" (star of dawn) and the Inkarakay peak in Cochabamba, where there are still pre-inca ruins.

The Willkakuti, known as the Aymara new year, is celebrated on June 21st in the pre-inca ruins of Tiwanaku.

Problems with this festivity:

There are only about 2 million people in Bolivia who identify themselves as Aymaras, and many of them are actually mestizos. Almost nothing is known about the Aymara culture as they have no written history and very little archeological evidence of their culture has ever been found. They were conquered by the Incas and deported as slave labor to the Inca Empire. Even the name "Aymara" is actually a Quechua word used to describe natives who are not Quechua. The word is not original to their true ethnic identity. There is actually no evidence that the origins of this festivity are Aymara. In addition, the location where they now celebrate this Aymara New Year, the ruins of Tiwanaku are not Aymara ruins. They belong to the Tiwanakotas, a very different and much older culture. Also there is concern that the ruins will be damaged by the crowds.
