Across the street from La Dolorosa Chapel is the most famous building in Cajamarca. When Atahualpa was taken prisoner by Pizarro and his band of men in 1532, the Inca emperor was held in a cell, which he promised to fill with gold and silver many times over if the Spaniards would spare his life. The so-called "Ransom Room" is a small, rectangular stone room, set in the back of a colonial courtyard, once part of Atahualpa's palace. It is made of unadorned Inca masonry -- the last intact example of Inca architecture in the city -- and is barren except for a red line drawn across one wall, supposedly the very line Atahualpa drew to demonstrate to the Spanish how high his men would fill the cell with treasures. No one knows for sure whether this was simply Atahualpa's prison cell or if it was indeed a ransom room. What we do know is that the Inca chief was later executed by Pizarro's men, presumably on a stone right here, even before the Incas had surrendered all of the promised riches. The Cuarto de Rescate represents a crucial moment in Peruvian history, a clash in cultures with ramifications for the entire continent, but it might take some imagination to conjure the drama of the moment. The large painting at the entrance near the ticket booth, of Atahualpa being burned at the stake by the Spanish, is not entirely accurate; after accepting baptism, Atahualpa was merely strangled to death.
