The Noble Hall, created on the upper floor in the context of the first extension of the Aquarium, was purposely designed to display the museum's growing collection.
This area, inaugurated and reopened to the public on 20 May 1943, the 45th anniversary of the Vasco da Gama Aquarium, still preserves the original furniture and the spirit of that time, celebrating the famous 'cabinets of curiosities', the ancestors of today's museums.
Dedicated to the curiosity of the first naturalists and their desire to explore the world, the exhibition revolves around one of the most beautiful pieces of the Dom Carlos I Oceanographic Museum Collection: the Logbook illustrated by Carlos de Bragança on the expedition that took him to the coast of Sesimbra in 1897.
