Raqchi, also known as the Temple of Wiracocha, is an important Inca archaeological site located in the Cusco region of Peru. The site was a major religious and administrative center in the Inca Empire, dedicated to Wiracocha, one of the most important deities in the Inca pantheon. The centerpiece of the complex is the massive temple with a central adobe wall that once stood nearly 15 meters high, flanked by rows of columns—an unusual architectural feature in Inca construction. The temple’s scale and design reflect the significance of the site as a place of pilgrimage and worship, with facilities for ceremonial feasts, storage, and lodging for travelers and priests.

In addition to the temple, Raqchi includes a number of colcas (storehouses), residential buildings, ceremonial baths, and an impressive network of aqueducts and canals, indicating its role as a strategic economic and spiritual hub. The site's layout suggests careful planning to serve both religious and practical purposes. Located along the Inca Trail system, Raqchi was a resting point for travelers and messengers (chasquis), playing a key role in maintaining the empire’s cohesion. Its preservation offers valuable insights into Inca engineering, urban planning, and religious life.
