The National Tile Museum (Museu Nacional do Azulejo) is a unique cultural institution in Lisbon, dedicated to the art of the azulejo—the traditional glazed ceramic tile that is a hallmark of Portuguese artistic heritage. Housed in the historic Madre de Deus Convent, founded in 1509 by Queen Leonor, the museum offers a comprehensive journey through the history of tile-making in Portugal, from the 15th century to contemporary times.
