History of the Palace of Versailles czar Peter the Great stayed at the Grand Trianon. His time at Versailles was used to observe and study the palace and gardens, which he later used as a source of inspiration when he built Peterhof on the Bay of Finland, west of Saint Petersburg. During the reign of Louis XV, Versailles underwent transformation but not on the scale that had been seen during his predecessor's reign. When Louis XV and the court returned to Versailles in 1722, the first project was the completion of the Salon d'Hercule, which had been begun during the last years of Louis XIV's reign
Palace of Versailles when the enemies of the King's chief minister, Cardinal Richelieu, aided by the King's mother, Marie de' Medici, tried to take over the government. The King defeated the plot and sent his mother into exile. After this event, Louis XIII decided to make his hunting lodge at Versailles into a château. The King purchased the surrounding territory from the Gondi family, and in 1631–1634 had the architect Philibert Le Roy replace the hunting lodge with a château of brick and stone with classical pilasters in the doric style and high slate-covered roofs, surrounding the courtyard of the original hunting lodge.
