On 9 October 2020, the Carmina Contemporary Art Gallery, situated to the east of Angra, was donated to the museum by its founder, Dimas Simas Lopes.

Called Do Mar e da Terra: uma história no Atlântico (Of Sea and Land: A History of the Atlantic), the exhibition explores the role of Terceira and the Azores in Portuguese history, from the settlement of the islands during the Age of Discovery to the present day, placing great emphasis on the strategic position of the Azores as the crossroads of the Atlantic.

Section 1 looks at the discovery of the islands of the Azores from 1427, the beginnings of settlement in 1439, and the development of agriculture based on cereal cultivation and livestock rearing.

Section 4 covers the 19th and 20th centuries, including the increased use of modern inventions, steps taken to improve the defences of the island, and Terceira's role in World War II, notably through the granting of access to Lajes Field airbase to the Allies.

Its most notable feature is its eclectic nature, or diversity, covering ethnography, weaponry and military equipment, painting, imagery, ceramics, costumes, musical instruments, and furniture, as well as transport and the inevitable wars in the region.

It stands close to the site of a small chapel built in the 15th century for the same patron saint by the sailor Afonso Gonçalves Baldaia, one of the first settlers on the island.

The walls are covered in tile panelling from the first half of the 18th century, narrating episodes from the life of Saint Francis, attributed to Valentim de Almeida (1692–1779).
