Museum
Aliança Underground Museum
Between Aveiro and Coimbra, in the village of Sangalhos in the Bairrada wine-producing region, this magnificent place is part adega (winery), part art museum. Guided tours take you beneath the winery to a vast 1.5km network of tunnels housing an extraordinary collection of African and Portuguese art. Also down here are cellars crammed with huge oak barrels of maturing wines and brandies.
