MS Collection Arouca – Mosteiro da Arouca
This five-star property from Portuguese brand MS Collection occupies the restored south wing of the Arouca Monastery, a vast 10th-century complex that still houses a museum and church. Historical details—arched cloisters, stone walls, carved wood—have been carefully preserved and woven into a minimalist-chic design that embraces modern touches like underfloor heating in the bathrooms, and deeply comfortable beds. Landscaped gardens feature a large pool, original water features, and trails spanning out to surrounding hillsides. There’s also a serene spa, elegant restaurant, and cocktail bar, making it the region’s first true luxury stay.
