The Douro Museum should be the first port of call for anyone interested in the culture and heritage of the Douro valley. Located in the region's unofficial capital, Peso da Régua, the museum occupies the Casa da Companhia Velho, a former wine warehouse on the riverfront.
Exhibits range from the historic to the modern. They cover not just the development of wine and port in the region in the permanent exhibition, but also its geography and a full insight into how people used to live in days gone by.
Should you need some further convincing, tickets (adult tickets cost around €6) also give visitors a complimentary glass of the wines that were once stored in the building.
