The Palace of the Grand Masters is another masterpiece built by the indefatigable Girolamo Cassar in the late sixteenth century. Perhaps unsurprisingly, it is the largest palace in Valletta. As such, it had constantly served lofty political purposes, either as home to the Grand Masters or the British governor or as the seat of the Parliament of Malta (1921-2015). This tradition continues today since the President of Malta chose this palace as his office.
