The Cathedral Basilica of the Assumption of the Virgin, also known as Cusco Cathedral, is the mother church of the Roman Catholic Archdiocese of Cusco. The cathedral is located on the Plaza de Armas. Building was completed in 1654, almost a hundred years after construction began.
Adjacent and joined to the cathedral is the smaller Iglesia del Triunfo, the first Christian church to be built in Cusco. The Iglesia de la Compania de Jesus, also on the Plaza de Armas, was built at a similar time as the cathedral.
The Cathedral, in addition to its official status as a place of worship, has become a major repository of Cusco's colonial art. It also holds many archeological artifacts and relics. The cathedral was designated a UNESCO World Heritage Site under the City of Cuzco listing in 1983.
The Incas built the temple known as Kiswarkancha on the main square in Cusco. It was the Inca palace of Viracocha, ruler of the Kingdom of Cusco around a century before the Spanish colonists arrived. The aboriginal name of this city was Qusqu. Although it was used in Quechua, its origin has been found in the Aymara language. The word itself originated in the phrase qusqu wanka ("Rock of the owl"), attending to the foundational myth of the Ayar siblings.
Near to the Kiswarkancha was the Suntur Wasi, an armoury and heraldry centre for the Inca royalty. When the Spanish conquistadores arrived in Cuzco, they decided to take down the temple and build their Christian cathedral in that prominent site.
The cathedral's construction began in 1559 on the foundations of Kiswarkancha. It is shaped like a Latin cross. The location of Viracocha's palace was chosen for the purpose of removing the Inca religion from Cusco, and replacing it with Spanish Catholic Christianity. Because 1559 was only 26 years after the conquistadores entered Cusco in 1533, the vast majority of the population was still of Quechua Inca descent. The Spaniards used the Incas as a labour workforce to build the cathedral.
