Rising from the plains of Portugal’s Alentejo region, Adega Mayor is as much an architectural destination as it is a winery.
Designed by acclaimed architect Álvaro Siza Vieira, the striking white building has become a landmark of Portuguese wine tourism, its minimalist lines blending seamlessly into the surrounding landscape. Inside, expansive production spaces, tasting rooms and a panoramic terrace invite visitors to slow down and savour the region’s rich wine heritage.
For those seeking a deeper connection to Alentejo, Adega Mayor offers an experience where architecture, wine and a strong sense of place come together beautifully.
