The Cavalinho: the first open-air Palaeolithic engraving in Europe.

The history of olive oil in Trás-os-Montes isn't just found in books. In some villages, it's inscribed in the stones of an olive press, in the iron of a press, in the memory of those who still remember seeing oxen turning the mill. Lavandeira, in the municipality of Carrazeda de Anciães, is one of those villages.
