After his brother D. Pedro V’s unexpected death in 1861 D. Luís, commander of the navy corvette Bartolomeu Dias ascended to the throne. It was the new monarch’s strong connection to the sea which led him to establishing the Museum of the Navy just two years later. After operating from the old navy yard and the palace of the Count of Farrobo in Sete Rios, the museum found its permanent home on the northern and western wings of the Jerónimos Monastery in 1962.

Besides the notable collection of sailing ships ranging from the 16^th to the 19^th centuries, here you can also find weapons, uniforms, navigational instruments and maritime letters. The royal vessels displayed at the Galeotas Pavillion are not to be missed. Neither are the cabins of the Amélia IV - the last Portuguese royal yacht that belonged to king D. Carlos and which he used for his last oceanographic campaigns.
