When the Spanish colonized Peru in the 16th century, they tore down the Incan temples and palaces, leaving the base level of original stone masonry in place. On top of those they built European-style white stucco walls, ornate baroque stonework, and intricately carved wooden balconies. This fusion of Incan and colonial architecture, particularly in Cusco, helped earn the city the designations of Historical Capital and Tourism Capital of Peru.
On May 21, 1950, an earthquake rocked Cusco, damaging approximately half of the city's buildings. The worst destruction affected old adobe houses and colonial-era churches, including the Church of Santo Domingo, which was built atop the Coricancha ("Temple of the Sun," dedicated to the Incan sun god). Spanish chronicler Pedro Cieza de León once marveled at the temple's "excellent masonry," noting that "the stones themselves are so well worked that no joining or cement can be seen." He was referring to the Incan technique of ashlar masonry, in which large, hand-cut stones are shaped to fit perfectly together—so well, in fact, that their structures survived the quake while newer additions crumbled.
Cusco's history stretches back even further, and more treasures are still being found. In 2008, archaeologists uncovered ruins of an ancient temple, roads, and irrigation systems credited to the pre-Inca Killke culture, likely dating back to the 12th century. Killke ceramics have also been found throughout the city. Due to its proximity to Machu Picchu, Cusco is sometimes thought of as merely a gateway to one of the New Seven Wonders of the World, but its own rich history has been attraction enough. In 1983, the United Nations Educational, Scientific, and Cultural Organization (UNESCO) designated Cusco a World Heritage Site, recognizing its extraordinary cultural significance.
