text: Honoré I (1523–1581) During the reign of Honoré I the internal transformation from fortress to palace was continued. The Treaty of Tordesillas at the beginning of Honoré's rule clarified Monaco's position as a protectorate of Spain, and thus later of the Holy Roman Emperor Charles V. This provided the security to allow the Lord of Monaco to concentrate on the more comfortable side of his residence rather than the constant need to defend it.
  The courtyard was rebuilt, the architect Dominique Gallo designing two arcades, stretching between points H and C. The arcades, fronting the earlier wing by Lucien I, each have twelve arches, decorated by white marble balustrading on the upper level. Today the upper arcades are known as the Galerie d'Hercule (gallery of Hercules) because their ceilings were painted with scenes depicting the Labours of Hercules by Orazio de Ferrari during the later reign of Honoré II. These arcades or loggias provide corridors to the state rooms in the south wing (today known as the State Rooms Wings). On the other side of the courtyard a new wing was constructed and the Genoese artist Luca Cambiasi was charged with painting its external walls with frescoes. It is thought that the galleries (B) to the north wing overlooking the harbour were built at this time.
  Further enlargements were carried out in order to entertain the Emperor Charles V in 1529, when he stayed four nights at the palace during his journey in state to Bologna for his coronation by Pope Clement VII.
