Museo Oro del Peru has a fantastic collection of gold artifacts from Inca and pre-Inca civilizations. The building has an extensive collection of military antiques upstairs and a vault downstairs with the gold collection.

The gold collection’s highlight is a tumi, a ceremonial Inca knife used for sacrifices (below). Most of the gold pieces are from the Lambayeque culture, which lived on the northern coast of Peru from around 700CE-1350CE. (The civilization was pre-Inca but then survived concurrently with the Inca as their subjects until the conquest). There are also some oddities, like a gold sculpture of a dog sticking its tongue out, an extensive collection of pre-Inca copper tweezers and anthracite mirrors.
