El Oso is a municipality (pop. 229) in the Spanish province of Ávila, in the autonomous community of Castile-Leon.

Megalith

The village takes its name (which means "the bear") from a megalithic monument outside the church. The monument in question may not have been intended to represent a bear. It is classed as a Verraco, a type of prehistoric monument found in central Spain, which shares its name with the Spanish word for a boar. Local legend identifies this example as a bear.
