Aramu Muru, Stone carving in Ilave District, El Collao Province, Peru

Aramu Muru is a stone portal carved into a rock face in the Puno highlands, featuring a central rectangular opening cut with precision. The structure demonstrates the craftsmanship of ancient peoples who inhabited this region.

Aramu Muru was found in the early 1990s and is considered an abandoned Incan construction project. No serious archaeological study has yet established when the site was first held sacred. Pukina, Lupaca and Aymara peoples lived in the Peruvian altiplano before the Incas, and the carving lies between Ilave and Juli, near Lake Titicaca.

The site's Aymara names carry its meaning: Ajayu Marka means "spirit city" and Willka Uta "sun door". Aymara pilgrims and New Age visitors gather here, and the legend of the priest's golden disk, said to have fallen from the sky, is told to explain the niche in the rock.

The site lies about 35 kilometers from Puno and is accessible via a regional road connecting several communities. Visiting requires preparation for high altitude conditions and expects a moderate walk to reach it.

The name Ajayu Marka comes from Aymara: ajayu means spirit, soul or energy, and marka means town or community. The alternative name Willka Uta combines willka (sun) and uta (door). The site lies midway between Ilave and Juli on the PE-3S highway, close to Lake Titicaca.
