Introduction
Choquequirao is an Inca archaeological site situated in the Urubamba Valley of the Andes, approximately 20 kilometers east of the world‑famous Machu Picchu. The name Choquequirao derives from the Quechua words “shuqlla” (stone) and “q'iraw” (a group of stone walls), reflecting the site's distinctive masonry. Though less renowned than Machu Picchu, Choquequirao holds significant importance for scholars studying Inca urbanism, religious practices, and territorial expansion. Its relative isolation, combined with well‑preserved structures, offers a rare glimpse into Inca architectural techniques and spatial organization outside the main centers of power.
Unlike the extensive tourist infrastructure surrounding Machu Picchu, Choquequirao remains largely undeveloped, preserving its natural surroundings and contributing to contemporary conservation efforts. The site’s accessibility has improved only in recent decades, leading to increased academic interest and a gradual rise in visitor numbers. The following sections provide a comprehensive overview of Choquequirao’s geography, history, architecture, excavation record, and its relationship with Machu Picchu and the broader Inca world.
Geographical Setting
Location and Topography
Choquequirao is perched on a steep cliff overlooking the Choquequirao River, a tributary of the Urubamba River. The site sits at an elevation of approximately 3,400 meters above sea level, placing it within the high Andean puna ecological zone. The surrounding landscape is characterized by rugged terrain, intermittent streams, and terraced agricultural fields that evidence the Inca’s sophisticated land‑management practices.
Accessibility to Choquequirao is limited by the surrounding mountain ridges. The primary approach involves a 12‑kilometer trek from the town of Machupicchu on the east side of the Urubamba Valley. The trail passes through a series of hanging gardens, agricultural terraces, and natural rock formations, providing both a challenging and rewarding experience for hikers and researchers alike.
Climate and Ecology
The region experiences a wet season from November to March, with rainfall averaging 600–700 mm annually. During the dry season (April to October), precipitation is minimal, and temperatures can drop below freezing at night. This climatic pattern has influenced the preservation of stonework at Choquequirao, as limited moisture reduces the rate of weathering compared to more humid environments.
Flora in the area includes high‑altitude grass species, dwarf shrubs, and occasional stands of hardy pine trees. Fauna comprises Andean condors, mountain tapirs, and various small mammals adapted to high elevations. The presence of these species is indicative of the ecological resilience of the Andean highlands and provides context for the Inca’s subsistence strategies.
Historical Background
Pre‑Inca Occupation
Archaeological surveys have identified evidence of pre‑Inca cultures, notably the Wari and Chanka peoples, in the vicinity of Choquequirao. Ceramic fragments, lithic tools, and petroglyphs dating to the 12th and 13th centuries AD suggest that the site was a place of cultural significance before the rise of the Inca Empire.
These earlier inhabitants utilized the strategic location for defensive purposes, as well as for controlling trade routes that connected the highlands with the coast. The subsequent Inca conquest and integration of the area demonstrate the dynamic interactions between different Andean societies during the late pre‑classic and early classic periods.
Inca Development and Purpose
Historical records indicate that the Inca expanded their influence into the Urubamba Valley during the reign of Inca Huayna Cápac (c. 1471–1487). Choquequirao’s development likely began during the late 15th or early 16th century, as part of a broader strategy to consolidate control over the region and to establish satellite centers that reinforced Inca administrative and religious authority.
Scholars hypothesize that Choquequirao served multiple functions: as a regional administrative hub, a religious sanctuary, and a strategic military outpost. The layout of the site - comprising plazas, temples, and residential complexes - supports the notion of a multifaceted center designed to integrate governance, cosmology, and defense.
Contact with the Spanish Conquest
During the Spanish conquest of the Inca Empire in the early 16th century, Choquequirao remained relatively isolated from the main centers of conflict. Consequently, the site experienced less direct devastation compared to Machu Picchu or Cusco. Spanish chroniclers mention the region’s strategic importance but provide limited details on Choquequirao itself.
Post‑conquest, the site fell into disuse and was gradually abandoned. Its remote location contributed to the preservation of many structures, shielding them from looting and repurposing that affected more accessible sites.
