Alphabet oh the demarcations

Object of the Month - April, 2026

Every month the Museum of the Oldest Appellation in the World highlights one of the many objects that are part of the collection shown in our permanent exhibition. Come and discover the object of the month and find out more about our history.

For April, the Museum of the Oldest Appellation in the World has selected as "Object of the Month" the register in which the Company recorded and listed - in alphabetical order - the demarcations carried out in the Alto Douro wine region. In accordance with its objectives and statutes, the Company’s primary duty was to ensure the total and absolute separation of Alto Douro wines destined for export from wines originating elsewhere that lacked the quality required for international markets, and which, consequently, were to be used solely for local consumption.

Fittingly, this volume is displayed in the exhibition section dedicated to the public works undertaken by the “Companhia Geral da Agricultura das Vinhas do Alto Douro” during its initial period of operation as a royal chartered company. This section highlights the work carried out by the Company in demarcating the Alto Douro wine region, as well as its pivotal role in elevating Port wine to the status of national symbol.
