On 24 June every year the winter solstice is celebrated, in other words the beginning of the Andean New Year: Inti Raymi. It is celebrated in the Fortress of Sacsayhuaman, Cusco.
The winter solstice begins on June 21st but according to the Incas, the sun stays in the same place until the 24th when it finally rises.
The celebration of the event starts at 8AM on the main plaza of the City of Cusco in front of the Coricancha, the rainbow Inti Raymi flag is raised while a mass takes place in the cathedral.
