On Llanguil Hill, only 8 km
northeast from the City of Cajamarca, there are living rock excavations,
appearing at a distance to be a multiple array of windows. The so-called
Ventanillas (Niches) of Otuzco (2,850 m.a.s.l.) are actually part of an old
cemetery of the Cajamarca Culture, which niches are neatly arranged in rows.
Apparently, this was an important place for honoring ancestors, which remains
may have been removed from their original tombs to be deposited in this
necropolis. Archaeologists have been able to identify two types of niches: the
simple type, for the majority and the multiple type, comprised of a corridor
flanked by lateral niches. (PromPerú)
