The Sacred Valley of the Incas or the Urubamba Valley is a valley in the Andes of Peru, 20 kilometres (12 mi) at its closest north of the Inca capital of Cusco. It is located in the present-day Peruvian region of Cusco. In colonial documents it was referred to as the "Valley of Yucay." The Sacred Valley was incorporated slowly into the incipient Inca Empire during the period from 1000 to 1400 CE
