The Museu da Oliveira e do Azeite sits near the Tua in the old Moagem Mirandelense mill. It is a small but useful stop, especially because olive oil is not just background scenery here; it is one of the things that shapes the economy and table of Trás-os-Montes.
The museum covers the olive tree, harvest, pressing, uses of the oil, and the old milling rooms. It works best as context before lunch, when a plate of alheira or grilled meat suddenly feels more tied to the surrounding hills.
