Not everything in Paraguay's highlands is ancient wilderness. Castillo Echauri stops first-time visitors in their tracks and for good reason.

Built between 1985 and 1990 by architect Guillermo Echauri, this striking stone castle sits within the Cordillera del Ybytyruzú, just outside the town of Colonia Independencia.

Echauri designed it as a personal tribute to his ancestors from Navarre in northern Spain, a region defined by its medieval fortresses, and the result is something that feels genuinely out of place in the best possible way. Massive stonework, concrete reinforcements and a unmistakably medieval Spanish silhouette rise from 17 hectares of beautiful natural surroundings.

Inside, the atmosphere matches the exterior. A 17th century suit of armour stands guard, stone tables and chairs recall the atmosphere of feudal Spain, and the details throughout reflect a builder who took his homage seriously. Though the castle was never fully completed to its original design, what stands today is more than enough to leave a lasting impression.

Originally a private weekend retreat for the Echauri family, the castle now welcomes visitors for guided tours and photo sessions. It is one of those stops that needs no elaborate explanation: guests simply arrive, look up, and reach for their cameras.
