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.

Olive oil is one of the most emblematic elements of the Mediterranean Diet, recognized by UNESCO as an Intangible Cultural Heritage of Humanity.
