Limatambo, 80km west of Cuzco, is named after the Inca site of Rimactambo, also popularly known as Tarawasi , which is situated beside the road, about 2km west of town. The site was used as a ceremonial center, as well as a resting place for the Inca chasquis (Inca runners who delivered messages over long distances). The exceptional polygonal retaining wall, noteworthy for its 28 human-sized niches, is in itself worth the trip from Cuzco. On the wall below it, look for flower shapes and a nine-sided heart amid the patchwork of perfectly interlocking stones.
