Don Miguel was not only a passionate wine producer but also a great lover of art and culture. He created a museum in the castle, where he stored his collections of sculptures (mostly from the Middle Ages and Renaissance periods), altars, textiles, furniture, paintings, coins, glass products, and ceramics which he had been collecting for years. He also enlarged the collections of the monastery library which now stores around 100,000 volumes, including manuscripts, incunabula, chronicles, and other bibliographical treasures. The monastery also hosts the Wine Museum with parts of a retained wine cellar as well as a historical collection of 750 bottles showing the history and growth of winemaking.
