This floor is given over to the traditions and techniques of Macau fishermen, as well as other regions of South China. In the different exhibits, models of vessels, representations of different fishing techniques, costumes, and implements used at the shipyards can be seen, among other objects. Reference is also made to the special festivals of these communities.

This exhibition is presented as realistically as possible, through the continuous presentation of video films showing various fishing techniques and nautical workmanship and construction, through a diorama showing the location of different fish species in the surrounding waters of Macau, through a small theatre with four movable scenes portraying the legend of the Goddess Á-Mà

Visitors can also observe historical exhibits, such as a model of a dragon boat largely constructed of whalebone. This object was preserved in a local temple as a sacred relic and kindly donated to the museum in 1990.

On the Mezzanine Floor there is a display cabinet with 10 models of traditional Portuguese vessels. A multi-media system is installed above the model that shows a short documentary on the relevant vessel.

This floor also houses a magnificent scale model of the "Sagres" training ship made by craftsmen in our own workshop.

This exhibition area focuses on various aspects of Portuguese and Chinese maritime history, covering the period from the fifteenth to the seventeenth centuries.

Here, the Discoveries are represented in the form of models of Caravels, Frigates and nautical instruments which are complemented by video systems and electronic models showing routes taken by the explorers.

Also in this area there is a realistic model of a "Nau do Trato" (a merchant frigate) - which among other journeys, made commercial voyages between Macau and Japan. There is also a replica of a Namban folding screen.

Macau and its Harbour have special pride of place in this part of the exhibition; and they are represented by a three-dimensional model depicting the city during the seventeenth century with its harbour, walls and fortifications. The model has a system of illumination points which light up, allowing the visitor to find the location of the most important places.

Also on this floor, there is a display of a Dead-eye, a Block and a Repair Sternpost. These are archaeological discoveries of great historical value, which were unearthed in 1993 during reclamation works for the construction of the Macau International Airport. Following dating of these relics, it has been possible to deduce that they belonged to a European vessel of the seventeenth century which had been anchored in Macau.

The exhibition on the top floor mainly covers the areas of technology and maritime transport, dredging and navigation. In this area, the methods of explanation were considered quite carefully in order to add to the attractiveness of the exhibition.

Due to its importance as an aid to navigation, it has been considered necessary to highlight the model of the Guia Lighthouse. This was the first lighthouse to be erected on the South China coast, and today it is still extremely useful in guiding ships on their access to Macau.

Of no lesser importance is the exhibition of various nautical instruments dating from the eighteenth to the twentieth centuries. Among these, Octants, Telescopes, Straight Edges, Mariner’s Compasses, and various Sextants are displayed. The display dealing with tides, winds and water depth is equipped with an electronic board which allows people to visualize the use of a water gauge.

There is also a model of the Macau navigation channel, with its system of buoys and beacons. A visualization of its appearance at night is permitted with the activation of small lights depicting various navigational signals.

Above this floor a celestial dome-shaped ceiling was constructed representing the northern hemisphere. Astronomic navigation was, and still is, an important aid for seafarers. Through a manual system, the visitor can find various constellations, including his or her own astrological sigh.
