Horca del Inca, Copacabana

The Horca del Inca ("Inca Gallows") in Copacabana is an interesting trilithic structure used for astronomical purposes by the pre-Incan Chiripa people.


History of Horca del Inca

Despite its name, the Horca del Inca was built by the pre-Inca Chiripa culture in the 14th century BC as an astronomical observatory. Rituals on the winter soltice June 21 were also held here.

When the Spanish came along, they destroyed some of the site in the hopes of finding gold hidden there. Noting its resemblence to a gallows and mistakenly associating it with the Incas, they gave the monument its present name.

What to See at Horca del Inca

The trilithic (three-rock) structure resembles a gallows, hence its popular name. Between the two naturally upright rocks, the Chiripa builders placed seven horizontal rock slabs in precise positions that would enable observation of the heavenly bodies. On the equinoxes, the sun can be viewed as it reflects off the rocks.

There is only one cross-piece left in position today, thanks to the Spanish, and unfortunately the rocks have been decorated with graffiti. However, the ancient site still has plenty of ambience as well as fine views of Lake Titicaca and the town of Copacabana.

Getting There

The site is located on a rocky hill in the southeast part of town (see map). Hiking to the Horca del Inca is only for those of reasonable fitness and comfortable shoes, as the path is steep and rough. Boys hanging around by the base will usually offer to show the way for about $1; it is worth taking them up on it.
